Here is a study of muted neutral colors.
I tend to use a lot of the same colors (color schemes) especially when working in watercolor. It’s hard to break away… Watercolor looks most beautiful, me thinks, when mixed directly on the paper, not the palette. There’s a lot of guess-work, and a lot of just letting the pigment do what it wants, not what you want. But I think I’ve become a bit too careful, too controlling. This study helped me see that tendency. Wonderful!
