Storage: Watercolour Tubes

Increasingly, I want to use paint straight from the tube to get a more intense effect, so I need to find tubes easily - the tubes I threw into a drawer...and the writing is so small on them, it was taking ages! I temporarily had them sorted by colour in a plastic tray but I had too many paints...then I stumbled on this in Tiger (Flying Tiger in the USA - a wonderful Danish chain) and it turned out to be PERFECT! It is their Opbevarginsbokse (Storage Boxes), and comprises 3 tiered boxes that can be stacked in any order that lock together, plus a lid. Each box has 6 sections, so there's 18 sections in all. The sections are EXACTLY the right size for 5mL paint tubes! This might also work for people who can get to a Tiger shop :O)

My Winsor & Newton Artist's Watercolours are coded with numbers than ultimately run from 001 to 799 at present - though only about 100 are ever in use at a time, I have discontinued colours from 1979 to 2002, so those numbers I do need to consider. I split the top layer into 3 rows - "000", "100", "200" and each row has two sections e.g. "000-049" and "050 to 099". This allowed me to get all of them into the box with room to spare - there are two sections in the bottom layer free for something when the time comes.

View from above - showing the handled lid and the 6 sections of the top layer.

View from the front...yes I left the label on, I'm that much of a slattern.

The top layer from inside - all of these are Winsor & Newton Professional Watercolours but many different branding designs as I have paints from 1979 to present as I have a lot of discontinued old stock I got for £1 a tube this year.

The Svalbard Series

So, I've been painting a lot of botanicals lately for a meadow project I'm working on and they all involve many layers of glazing. Whilst they are drying, I've taken to doing sketches based on the aurora borealis - this has kind of now become a thing and it's had a lot of attention on Twitter so I'm now hashtagging them as the #svalbardseries - they are silhouettes based on actual Google Street View images from Svalbard, but with imaginary backgrounds. Here are some examples, thus far - two based around the town Longyearbyen and one more rural based near to a mining town. Important to note that St Cuthbert's Mill kindly gave me a block of Saunder's Waterford paper to review, gratis, and I've been suing it for these paintings and others to really test it out. It is in 140lb cold-press (CP/NOT) in their 'high-white' colour, which is a very pure, bright white.

This was originally going to be 'Gaia's daughter', but I figure Jörð is more appropriate. The miner is stood to the left of their house, his daughter is held in his arms.

Reflecting the aurora in the snow on the ground worked out really nicely in the end. I did the spattering effect with one of those spattering brushes that looks like a bottle-brush and you turn the handle - makes for a lovely fine spray!

Don't be confused by the name at the bottom - that was me noting down what to paint next (i.e. the painting above this one!) but I was going to paint Norway - this was prior to deciding to stick to Svalbard.

Three Jar Inspiration

UPDATE 15th June 2016: I've made some worksheets for this technique and put them on my Downloads page to help start people off.

We all struggle with a lack of inspiration for painting regularly - personally I started using painting a small botanical each evening and posting them on Twitter under #bedtimebotanical a good motivation (please feel free to join me in that!), but there's another method I also use - I call it "three jar inspiration". If you use it, please tweet it or tag it on YouTube (etc) with #3jarspaint so we can share with one another our outcomes. I came up with this for myself as a means to force myself to use a wider range of mediums and to stretch my range of what I paint/draw - it has worked really well for that!

You need:
* Three jars of any kind.
* Paper (typing paper or scraps, 3 colours is ideal).

Label the jars, if you like - the should be labelled "What" "Style" and "How" - the "How" jar is actually optional. If you only paint in one medium e.g. watercolour and you don't want to use any other media, you can stick to just two jars.

In the "What" jar, put pieces of paper on which you have written a whole load of subjects for painting - these can be really specific like "The Sea", "A Banana", "Two Sheep", "A Beetle", or can be more figurative like "Playtime", "Laughter", "Deep Love", "Gaia's Might". You can use anything you like! If you like to use images for reference, you could swap this jar for a shoebox full of postcards or printed out images, for example. If you don't use reference photos - or perhaps want to start to get away from them - you can stick to using words on slips of paper and then only look up a reference photo when you really need it.

In the "Style" jar, put pieces of paper on which you have written a wide variety of styles, such as "Loose", "Abstract", "Impressionist", "Tudor", "Cubist", "Decalcomania" - they don't have to be specifically painting styles - you could use -  "Steampunk", "Vibrant", "Twisted", "Nightmare", "Stormy", "Dreamlike", "Utopia" - use your imagination! Or for a REAL challenge, put in some names of painters you admire! I've put in names of YouTubers I love as it helps me to try out their distinctive styles!

In the optional "How" jar, put pieces of paper on which you have written the different media you have to hand - put each one in a few times, obviously. "Charcoal", "Papercraft", "Cardmaking", "Mixed Media", "Art Journal", "Oil Pastel", "Alcohol Ink", "Stamping", "Pyrography", "Oil", "Gouache", "Alkyd", "Crayon", "Chalk", "Chalk Pastel", "Acrylic"...

How it works!
All you do is firstly decide when you want to paint/draw etc - for me, it's 2200h, so whatever time it is, find another time maybe 12-24h before which will be the time you use the jars. For me, that's 0600h. I get up and first thing, I grab a piece of paper from each jar - that tells me what I am producing at 2200h so I have all day to think up what or how I'm going to do this - you could be doing "Wasp, Steampunk, Papercraft" one day and "Seascape, Loose, Watercolour" the next - or if you use names of artists you could end up trying to mimic Leonid Afremov's oil painting style using decoupage to create a banana - in this way it REALLY stretches you as an artist!

Even if you only use two jars (or one jar and one shoebox), you are still challenged with doing watercolours (or whatever) of "sunset over Mount St Helens in Picasso style" or "tip of a ball-point pen in an art deco style" - that's a great challenge! Happy painting!

Radio Silence

I've been hellishly busy of late and had a period of illness too, so I'm quite behind on content. I've got a LOT of videos made that I need to edit and upload - some great product reviews of budget watercolours and acrylics, watercolour papers and inks, including the Tim Holtz Distress Ink Sprays and the Dyan Reaveley Dylusions Ink Sprays - comparing the two products. 

Hope to be back up to speed within the week!

Colour Translation: Kingfisher

Continuing sharing alternatives to the Turner watercolours for Lyndsay The Frugal Crafter's watercolour tutorials, this week she used the following colours from the Turner range, which is really hard to get hold of in the UK and the EU, so I've recommended some Winsor and Newton professional grade colours and Cotman student grade colours that should work in the same way. I've embedded her video below, for reference when looking through what I recommend. 

If you have set up a palette based on my recommended colours, even my standard Essential Palette (12 colours that make for easy mixing) pretty much covers this, but as I don't recommend Winsor Yellow or Permanent Sap Green in that collection, you would need to buy those as "add ons" - my Complete Palette still doesn't have Winsor Yellow in it - this is "Hansa Yellow" in many other sets, and it's a semi-transparent, staining warm yellow, so you could substitute it for New Gamboge and get similar effects, but I would recommend getting Winsor Yellow itself as it's a single-pigment colour whereas W&N New Gamboge has 2 pigments in, which means it won't mix in the same way and it's much easier to end up with muddy mixes that way.

If you're using the Cotman range, you'll find most of the same colour names translate over, except where noted. My Student Palette does cover most of them (and has links for buying them on Amazon UK, where they are dominantly sold below the RRP of £2.60 per tube) but per the above, you'd need to make some additions, which I've annotated below.

Yellow Ochre, PY43 Natural Yellow Iron Oxide
This is a pretty standard Yellow Ochre so anything with the same name in another brand is going to work.
Permanent Yellow, PY154 Benzamidazolone Yellow 154
This is 730 Winsor Yellow (Winsor and Newton). A lot of manufacturers use names like this - "[manufacturer name] Yellow" for this pigment, or "Hansa Yellow", of course. There is no Cotman alternative to this colour, so you would need to make do with Gamboge (Hue) as the only semi-transparent, staining warm yellow in that series, but just be mindful that it isn't a close match to what Lyndsay is painting with so your work will look different - it could be a good exercise in colour-theory and mixing though, to try and match her mixes in slightly different ways?
Burnt Sienna, PBr7 Brown Iron Oxide
Virtually all Burnt Sienna watercolours on the market use this pigment, so an easy alternative should be possible.
Ultramarine Blue, PB29 Ultramarine Blue
This, again, is pretty easy to match in virtually any series.
Phthalo Blue (RS), PB15 Phthalocyanine Blue RS
Ditto - this will be universal - but will have different names, for example, Winsor Blue (Red Shade) (Winsor and Newton) or Intense Blue (Cotman from Winsor and Newton).
Sap Green, PG36 Phthalocyanine Green YS and PY110 Isoindolinone Yellow.
This is totally just a convenience mix so you don't even need it! You can either just mix together a Phthalo Green YS (such as Winsor Green (Yellow Shade)) and a Permanent Gamboge (such as New Gamboge ) or an Irgazin Yellow to get a viable Sap Green yourself. If you use it a lot, pre-mix them wet and set into a palette and avoid buying it. Alternatively, you can buy a Permanent Sap Green . It's worth noting that Hooker's Green is the same two pigments in different ratios, so you can add a little yellow to it and make your own Sap Green that way too. Be wary of the Cotman version of Sap Green  as it contains a lot of opaque red in the form of PR101 - an iron oxide pigment - which is obviously going to give you unusual results and muddy mixes quite easily- if you use Cotman, I would recommend you use Hooker's Green Light here and add a bit of yellow or yellow ochre to it to match true Sap Green.

Enjoy painting this project - it's a really beautiful kingfisher (a bird I've only ever seen once in my life, sadly)!

Product Review: Sennelier Abstract Acrylic Paints



My local art stores only stock Daler and Rowney (which I like CRYLA and System 3 ranges of) and Pip Seymour (which I dislike - they have a nice range of earth colours but I dislike the almost jelly-like texture some of the colours have) acrylic paints - so when the local big-box store started selling Sennelier Abstract Acrylic Paints, I was intrigued. None of the colours were ones I really needed, but I don't have a neutral gold so I picked up a pack of 028 Iridescent Gold for a mere £2.00 - it was on sale and is normally £4.00 there, and on Amazon UK it is £7.63, so this was a pretty good saving! When I got to the checkout, I was given a tiny pack of 385 Primary Blue for free as a sample. When I did my test comparisons below, I had assumed this would be either a Process Blue (i.e. Cyan) or a neutral blue, like a Cobalt Blue (Hue) - so I used the latter (System 3) for comparison. When I read the package and realised it was a Phthalo Blue (PB15:3 Phthalocyanine Blue BGS), I thought that calling it "Primary Blue" was a bit stupid - every painter the world over knows Phthalo Blue would be called Phthalo Blue, right? I don't get why they didn't use the normal name. I used System 3 707 Rich Gold as the comparison for the Iridescent Gold as it was the only gold I had to hand.




Sennelier Abstract are sold in pouches rather than tubes and come in at 120mL (4 US fl. oz.; 4.2 UK fl. oz.) - so let's normalise that to a current Amazon UK price of £6.36/100mL. In comparison, System 3 707 Rich Gold is £5.52 for 150mL (5 US fl. oz.; 5.3 UK fl. oz.), which normalises to £4.60/100mL. CRYLA 707 Rich Gold is £9.25/75mL (2.5 US fl. oz.; 2.2 UK fl. oz.), which normalises to £12.33/100mL:

Normalised prices:
Sennelier Abstract 028 Iridescent Gold = £6.36/100mL.
Daler & Rowney System 3 707 Rich Gold = £4.60/100mL.
Daler & Rowney CRYLA 707 Rich Gold = £12.33/100mL.

That puts Sennelier Absract halfway between the two in terms of price. The paint coming in pouches intrigued me - not as easy to store as tubes I guess. The paint is marketed as a "heavy body" paint but to be honest, even just feeling it through the packaging, it's really not - it's a little heavier than System 3 Standard Body but nowhere near as thick as the Heavy Body or CRYLA versions.

So how do they look? I painted them onto Daler & Rowney System 3 Acrylic Paper with a dry Simply Golden Taklon 1" flat wash (one of my favourite ranges of acrylic brushes even though they are the cheapest things around!) to see how they came out. The advertised properties of the four paints are:

Sennelier Abstract 028 Iridescent Gold - PY3 + PBk7 (Hansa Yellow 10G + Lamp Black) on mica, lightfastness n.r. (not listed), transparent.
Daler & Rowney System 3 707 Rich Gold - PW6 + PR101 (Titanium White + Synthetic Iron Oxide Red) on mica, lightfastness ***, transparent.

Sennelier Abstract 385 Primary Blue - PB15:3 (Phthalocyanine Blue BGS). Lightfastness ***, semi-transparent.
Daler & Rowney System 3 110 Cobalt Blue (Hue) - PW6 + PB29 (Titanium White + Ultramarine Blue), lightfastness ***, opaque.




Top to bottom: Sennelier Abstract in Primary Blue and Iridescent Gold then Daler & Rowney System 3 in Cobalt Blue and Rich Gold.

So, my verdict on them. Firstly, the body really is not heavy body - they're very liquid and actually reminded me of Daler & Rowney Graduate Acrylic in that regard. The colour intensity is quite good and in the image above, I applied roughly equal blobs of each of the 4 paints - you can see the two blues have a similar pigment load, but the golds are a bit different - the Sennelier gold has clear patches of paper showing through - but the Daler & Rowney gold doesn't.

A close-up of Sennelier 028 Iridescent Gold - you can see clear patchiness where the pigment load just isn't as good and the tooth of the paper really shows through. It's advertised as being a transparent colour, so I would expect that to some degree, but not patchiness - that's not acceptable. The sparkle was pretty much as one would expect and the colour a nice neutral gold - I have no negatives I can say in those regards.

And now Sennelier 385 Primary Blue - the coverage is better here but it does seem thin in a few places - for a semi-transparent colour, that's kind of usual but I did feel it just didn't want to go as far on the page as the System 3 colours did.

Here is the Daler & Rowney System 3 707 Rich Gold (Imitation) for comparison - you can see much better coverage and even in a standard-body paint, there are clear brushmarks - a heavy-body paint should show those, which shows how totally not a heavy-body paint the Sennelier ones are. The coverage is good and even - there is no patchiness and whilst the texture of the tooth shows through, you can't physically see bare tooth.

And Daler & Rowney System 3 110 Cobalt Blue (Hue) - this still shows brush-marks like the above even though it's standard-body - there's a bit of thin, patchiness at the top left - where the tooth does show through - this is an opaque colour so it does fall down a bit on that regard but I think this is more a symptom of my brushwork as I threw this one down last of the 4 before getting something to eat!

Sennelier Abstract Heavy-Body Acrylic Paints
Packaging:
Looks: *******--- 7/10
Recyclableness: Not Known
Readability: ********** 10/10
Ease of use: ********** 10/10

Product:
Quality: ******---- 6/10 (it was pretty good in terms of the colours themselves and the pigments used, but as it wasn't heavy-body, I felt this was totally misleading - the patchy nature of the application compared to System 3 really let this paint down, too)
Value for Money: *****----- 5/10 There are better quality, true heavy-body acrylic paints with similar grade pigments available at a lower price - therefore I cannot consider this good value and the outright lie re: being heavy-body is not good at all.

OVERALL RATING: 4/10






Starting Off - The Student Palette

Yesterday I posted a suite of 3 professional palettes for those who want to upgrade to artist-grade paints from student-grade ones. Today, I've decided to throw another into the array - it is based on my Basic Palette of 12 colours and it's called the Student Palette (oddly enough), it is based on Cotman Water Colours, so that has a nice easy price as they are always sold at a single price-point. The RRP is £2.60 per 8mL tube, but the Amazon links below should give some better deals, as Amazon usually manage to do. This palette gives you a cool, warm and earth tone of each Yellow, Blue, Red and Neutrals, which is more than ample. To be honest, if you find you need to go beyond that once you're experienced, I'd just upgrade immediately to professional colours - it'll work out far more economically in the long run!

The reason I rate Winsor and Newton Cotman student watercolours so highly is the quality - you can view my video on the differences to find out more on how they compare with the professional colours. If you compare this set with the professional colours of the same names, with the exceptions of the "hues", they all have the same pigments as the artist's grade - just less of it, so some are padded out with "fillers" - a chalk-like mineral, which can make student watercolours feel a bit "gouache-y"  and more opaque than an authentic one, but Cotman are pretty good. As for what hues are, they are simply "honest fakes" - real Cadmium Yellow uses a cadmium sulfoselenide as the pigment (PY35), the "hue" in the Cotman series uses two dyes - diarylide yellow FGL (PY97) and hansa yellow 65 (PY65) - to give a pretty close match the real thing as:

1) they're much cheaper to manufacture (true Cadmium Yellow is one of the most expensive colours, at £8.80/tube = £17.60/10mL, whereas this "hue" is a mere £2.60/tube = £3.25/10mL - just under 20% of the price!) and 

2) less toxic, but they won't mix in quite the same way or behave in quite the same way - hues of normally granulating colours have a granulation medium added to them to try and make them look more authentic)

The Student Palette
[Est. price based on RRP of £2.60 per tube, £31.20 = US$45.60 = €40.00 = C$57.00 = A$60.00]
This palette is essentially the same as my 12-colour Basic Palette of professional watercolours - I've made one substitution, basically, as one of the colours doesn't have a Cotman version or even a close equivalent.

Going Pro - Moving from Student-grade to Artist-grade paints

I get asked a lot, both directly and through helping other content-creators to clear the questions they're getting on their vlogs and blogs - we all get asked "which paints are best for beginners?" (hence my various reviews on YouTube), and lately I've been asked:
If I want to move from student-grade watercolour paints to artist-grade paints, which colours should I get first? How many do I need?
Well... I currently have nearly 50 colours, but I do not recommend that a beginner or someone moving from cheaper to more expensive paints does that! For a start, it's a huge investment (about £250 = €319 = US$365 = C$458 = A$480) to do that kind of thing! I'm a fan of having a limited palette and you probably need to think about what kinds of things you usually paint - someone who does seascapes might be able to justify some extra blues, someone who paints botanicals might need pinks and greens. You might also want to make some additions or substitutions on the grounds of opacity, like for example, I suggest Cadmium Yellow as your Warm Yellow, but you might prefer a transparent Warm Yellow instead/as well, in which case perhaps New Gamboge or Winsor Yellow [Hansa Yellow] would be suitable.


The 24 colours I currently use the most - "Jane's Grey" bottom left is 1:1 mix of French Ultramarine and Burnt Sienna - I mix them wet and dry them into my palette - it's much better than Payne's Grey. The equivalent I have included in my palettes below is Neutral Tint, as it's more convenient for the beginner.

Paints essentially fall into both single-pigment and mixed-pigment paints - some of those mixed-pigment paints are what we call "convenience mixes" - ones you can just throw together yourself, but the mix saves you time - which is worth it when you're a professional who needs to fire out a certain number of paintings every day to make a living, but not for an amateur or a semi-professional, really. Take Sap Green - a common earthy green with a yellow undertone, used in botanical paintings - the brand I use (Winsor & Newton Professional Water Colours, 503 Permanent Sap Green) is a mixture of PY110 Isoindolinone Yellow and PG36 Phthalocyanine Green YS - so, I could save money and just mix Gamboge with Winsor [Phthalo] Green Yellow Shade, and avoid having to buy this. You can mix them when you paint with them, or, you can blend them from the tube and dry into your palette as a mixture.

I'm going to recommend THREE palettes here - the Essential Palette of 8 colours (for those new to watercolour or upgrading to professional paints for the first time), the Basic Palette of 12 colours (for those with a bit more experience or who want to have a few more convenience mixes and a bit of a wider gamut) and the Complete Palette of 24 colours (which is pretty much what I use most of the time and is an adaptation of Jane Blundell's Ultimate Mixing Set based on what I use every day - so the most useful colours in my opinion. All are Winsor & Newton Professional Water Colour as they are a range I highly recommend - I have linked to Amazon UK for tubes only because buying half-pans is false economy! I can pour 2-3 half pans from a 5mL tube and yet the price of a half pan is nearly the same - so you're paying 2-3 times too much if you buy half pans! 

Note the sets are designed so that if you buy the Essentials Palette, all you need to do is add 4 more colours to 'upgrade' to the Basic Palette and then another 12 to get the Complete Palette nicer than having to buya whole load of new paints each time! I'm sure you can get fairly close colours in the Cotman range of student watercolours if you're a total beginner and don't want to or can't afford to take the plunge into professional colours - if so, the UK prices would be Essential, £20.00; Basic, £30.00 and Complete, £60.00 - regional price differences will apply, obviously! 

The Essential Palette
[Est. cost = £57.25 = US$83.64 = €73.07 = C$104.99 = A$109.96 - keep in mind these are RRPs - the Amazon UK links below give much better deals!]

This is really the absolute basics - I've cut it down to just 8 colours - a cool and warm of each Yellow, Red and Blue and a couple of useful neutrals. This is where a beginner should start - it isn't cheap as it's high-quality artist's paint, but a 5mL tube of each colour could easily last 12 months or longer! It'll seem like a big outlay - and it is - but it will last you a long time and will be a fairly easy conversion from perhaps a small student-grade mix.

347 Lemon Yellow Nickel Titanate [cool yellow] PY53 - £8.80
086 Cadmium Yellow [warm yellow] PY35 - £8.80
502 Permanent Rose [cool red] PV19 - £6.70
094 Cadmium Red [warm red] PR108 - £8.80
707 Winsor Blue [Phthalo Blue] Green Shade [cool blue] PB15 - £5.90
263 French Ultramarine [warm blue] PB29 - £6.45
074 Burnt Sienna [warm neutral] PR101 - £5.90
744 Yellow Ochre [earth yellow] PY43 - £5.90

The Basic Palette
[Est. price from scratch about £90 = US$131 = €115 = C$165 = A$173 - again, keep in mind this is based on RRPs - the Amazon UK links below will give you much better deals! Est. upgrade price from Essential Palette £33 = US$48 = €42 = C$61 = A$63]

12 colours that I think everyone needs and everyone can work from - I've included optional extras below that people who paint certain subjects might find useful - feel free to comment on this post if e.g. you find Cadmium Orange necessary for landscapes and I'll add it into the post as a suggestion.

I split colours into Warm, Cool, Earth and Dark - this palette includes one of each of the first 3 categories for Yellow, Red, Blue and Neutrals. Darks are included in The Complete Palette, below, as are Greens and Purples.

347 Lemon Yellow Nickel Titanate [cool yellow] PY53
086 Cadmium Yellow [warm yellow] PY35
744 Yellow Ochre [earth yellow] PY43

190 Cobalt Turquoise [earth blue] PB28, PB36
422 Naples Yellow [cool neutral] PW6 PBr24
074 Burnt Sienna [warm neutral] PR101
076 Burnt Umber [earth neutral] PBr7, PR101, PY42

The Complete Palette
[Est. price from scratch about £180 = US$262 = €260 = C$330 = AS346 - again, keep in mind these are RRPs - the Amazon UK links below will give you much better deals! Est. upgrade price from Basic Palette about £90 = US$131 = €115 = C$165 = A$173]
This builds on the above and comprises 24 colours that have enough convenience-mixes to make working en plein air a lot easier! As well as the Yellow, Red, Blue and Neutral groups, above, I've added Green and Purple. Each group contains 4 colours - a cool, warm, earth and dark. You could make substitutions to personal taste - like using Brown Madder instead of Indian Red or maybe Light Red as another alternative. I've used Genuine Rose Madder instead of Permanent Rose many times as I simply prefer it.
