I love these pallets. I have one for my warm yellows, 1 for cool yellows and you can write on the 2 big wells with the colors that are above ;if you use a woodless graphite pencil, it won't rub off easily. This way I know the exact color and color bias for my red, blues, yellows, violets, greens, and oranges. I find I only need one for my white, black/grey tints and earth tone water colors. For stains, I clean off with olive oil then follow with soap and water so oil doesn't get into my watercolor pigments.
