I thought you might like to see the layers I did to arrive at this strange but I think pretty background color. Just remember don’t do it in a journal because it may leak thru. The above rectangle is 8 washes of different colors. The one with Maestro Z is 16 washes.
Sorry about the colors in the following photos being off. I did take a photo after each new wash.
Cerulean is the first layer.
Layer 6 cerulean second go round.
Cerulean layer 8. Second go round the washes were more opaque. All of the plots are opaque of you do not use thin washes. U will get a very dark color this way. The sample really is almost an olive green.
If u want to make it as dark as the maestros photo. Reverse the above order and then do 8 layers backwards. Then add 8 more layers like the above eight.
