Here's a quick artist study I did in Gouache of a painting by James Gurney. The purpose of this test was to get a full range of colours with a Tryad of only Cyan, Yellow and Magenta. The diamond shape in the top left is used to test the different hues that I can achieve with the chosen Tryad. Any critique would be welcome! (I ran out of yellow so I couldn't finish the background) Original painting: http://gurneyjourney.blogspot.com/2020/09/triads-now-available.html
