I was irritated and then relieved to find that I had left my colour wheel back in Canada, and that there was not one for sale in any shop I tried in Bahrain (they are on order….). So I had no alternative but to create my own, from mixing paints myself. This was a really useful exercise as it was very difficult to mix accurately and it made me inspect tones, add tints very carefully. I ended up making up several, so that I could also play around with them, cut them up and turn around etc.
