There is a block in below! I started by under painting the whole board with viridian green and transparent red oxide. Then I used a white with a touch of transparent yellow oxide, and touches of viridian and purple lake to block in the whites. I try to make warm whites! It's hard you have to keep comparing with the surrounding colors! It's a balancing act this painting game. Anyhow as always I mean to take more pictures to show the process. Hope you have a great weekend!
