I wasn't in the mood for a big painting this weekend, so I decided to do colour swatches from the book "Blue and Yellow don't make Green", by Michael Wilcox. I was reminded of it by a comment from Ruth McCabe on Facebook recently. I've had that book a few years now, and every so often, I go back to it. Each time I do, I'm really glad. I was finding that the last few watercolours I did were not great in terms of hues - I was using nice colours: Indigo, Prussian blue, Madder red, but the overall effect lacked oomph. When that happens, it's time to get back to basics and good colour mixing!
The colours I was playing with this weekend were cadmium red (PR108), violet red (PV19), cerulean blue (PB35) and vanadium yellow (PY184). I can get really engrossed in my little colour squares, and I spent hours mixing and admiring them. I found that some of the mixes were really vibrant.
