Buying the most staurated color of a group, will give you the most flexibility. Its easy to lighten a dark color. Even if you love green, buying all of the greens will limit your ability to create different looks. This chart is meant to organize by color group, and saturation, to expand your range and maximize your budget.
I’d love your feedback on this. Is this something you do? Or do you find her colors so subtle it is too hard to mix them. Do you have a few favorite colors you use most of the time?
