What I did back when I painted miniatures was that I had a small box with the colors, and lent it to my friends, on the condition they added one color for every miniature they painted with it. Total win-win. It cost them 2.50 per figure, and the range of colors ever increased. In the end, there were over 30 pots in the box.
