I could never figure our how to paint watercolor charts. Mix 2 colors first or put in layers? How to keep values? Mix 50%-50% or how to check if the proportion is not precise? How to keep these small squares accurate and lined? If I add a bit of cool color to the warm mix - how to show the interesting result in the chart?
But in the village where I am now I have plenty of free time so I decided to try the chart making. Not sure if I made a treasure or a useless stuff, though.
And few watercolor studies:
