Good, but one frustrating problem – LiquidSketch Review

This would get 5 stars from me but there is a problem with some of the colors mixing without having any contact at all. Sometimes if the paint just sits there without moving it will start to change colors and mix all on its own. It's frustrating as I sit and think and the colors just change if I don't move fast enough.
