Colorsets like this suck. All you did was make a small hue scale of several different colors. The worst way to go about making a colorset (other than greys and browns) is to just make a bunch of hue scales. You need more variety than that.
Do what default does. Think of different rows (Standard, Bold, Soft, Trans, ect) and then fill in the blanks from there. Don't just do hue scales.
Also please correct me if I'm wrong.. I'm not 100% sure if the correct term is "hue scale" :3Edit:
I see two purples.
Either you don't know what purple is or you're seeing something nobody else is...
