As foretold by the gods, I have indeed swapper out the yellow in my latest painting for pistacio (and pale olive)! I like this much better, although there's still a long ways to go before this is worthy of even a cheap hotel room wall. (Dream big!)
I'm still getting the color situation straightened out. A lot of my typical black and white outlining might do wonders here. If not, I'll probably do it anyway BECAUSE I CAN'T CONTROL MYSELF!
