Ah, gouache – lovely, chalky gouache. I have added a bunch more color to the background, so that it moves from pink to yellow to blue, which seems like a fairy-tale-sky sort of thing to do. And I've started painting in the fur accessories on our damsel's ensemble.
Now you can start to see what I'm trying to do with the two kinds of paint: the reds I used for the watercolor are preserved as the shadow, and the gouache fills in where the light strikes.
I have enpinkened the reflected light on the edges of the fur. Reflected light color shifts are the principle on which the buttercup-under-the-chin test for bed-wetting operates.
