Nine Colour Mixing Grid

I've been sorting through some large sheets of paper and came across this chart from many years ago. I was always frustrated that a normal mixing chart only showed one or maybe two possible mixes, so I created this one to show 18 possible mixes.

The grid is 27cm x 27cm, created with 9 rows and 9 columns of 3cmx3cm squares. Each square is divided again to create 9 1cm x1cm squares. It's a fiddly to draw up and an even bigger fiddle to paint, but rather interesting. On single square can not really show the full range of possibilities - especially with interesting mixing neutrals like phthalo blue and cadmuim red, which creates Indian red hues, Prussian and indigo hues and a lovely mixed black. (I'd recommend using pyrrol scarlet rather than cadmium red as a warm red though)

It was made with a warm and a cool red, yellow and blue as well as three secondaries - orange, purple and green. 

The diagonal line of squares from top left to bottom right just show 9 variations of each of the 9 colours, which were lemon yellow, cadmium yellow deep, perinone orange, cadmium red, crimson red, imperial purple (mixed from PB29+PV19), ultramarine blue, phthalo blue and sap green. 

I'd use very different colours today - but this is just one of the many and varied charts I created to test out colour palettes. More mixing charts can be seen here, gouache mixing charts and wheels with a split primary palette here and some sample triads here.

They are labelled with pigment supplier and pigment numbers where known.

These pigments may have been too expensive, out of stock, difficult to get hold of or not of interest to make more, but they are shown here as it is so helpful to know what pigments from various suppliers actually look like when made into paint. (Any that have since been made available are noted in the captions)

Elizabeth has also created beautiful samples of some rather nasty pigments. It is fabulous to see these historic tough dangerous (and/or fugitive) colours in the flesh! Vermilion is a mercury sulfide. Mimium (Red Lead) is created by heating white lead. It would turn yellow then orange. Realgar is a natural mineral of arsenic sulfide, closely related to Orpiment
Rivervale Handmade Watercolour Samples - Vermilion, Minium (Red Lead), Realgar.
Lead Tin Yellow is a highly poisonous lead stannate - and oxide of lead and tin. Gamboge comes from the sap of the Garcinia tree and is a diuretic - it is also fugitive. Orpiment is yellow arsenic sulfide.
Rivervale Handmade Watercolour Samples - Lead Tin Yellow Pale, Gamboge, Orpiment.

We are very lucky that these poisonous pigments have been replaced with safer alternatives!

Happy painting :-)

ARTescape 2018

I'm excited to have been invited to teach at the Cairns ARTescape for 2018 - a week long workshop series in beautiful North Queensland, Australia. We'll be based in the Botanic Gardens Arts Precinct - what could be more perfect?

I'll be teaching a 5 day Watercolour Bootcamp - a great workshop for those relatively new to watercolour, or even more experienced artists, who want to really get to know and understand how this fabulous medium works. We'll set up the perfect palette for each student, explore the many characteristics watercolours, create useful mixing charts and colour wheels and paint a number of studies and more detailed paintings exploring a range of techniques and some interesting triads.
