This palette has a lot of different shades for each colour. It doesn't mean you have to use all shades when dolling. I usually limit myself to 5-colour palettes. The variety of shades is there so that you can make both pale clothing and dark clothing with the same palette. The left column is the brightest, the one in the middle is a sort of in-between, and the one at the right has the lowest saturation.
For the White palettes, the last highlight colour is 100% white.
