One of my online groups is working on blushing whites. Not pure white of the paper but a blush of color over then. Jeanne Dobie talks about this in her Making Color Sing book and says you put half-tones next to those blushing whites and you can move the color from warm to cool, etc. You can even make a pure white seem like it's a warm or a cool. Interesting. So we're playing with that. The first go-round, I put too much pigment in so had to go back and add more water and just a touch of the pigment. You can see the swatches in the 2nd set but just barely. It's harder to get the hint of color than you think!
