So in Art Class, we had to pick three paints, which are outlined in sharpie below. From those three paints, we had to create a page full of every possible color mixing combination and come up with as many as possible.
   It turned out to be very satisfying looking, especially because I discovered I could make the paint more watery and thin it.
   One of the conditions were we could not use black or white. HA! I found a loophole, teacher. Boom - lighter colors without mixing in white.

Unless my counting is wrong, there are 215 mixed colors shown above, including the three colors I was given to begin.
     Here are my instructions. Keep in mind: these were Tempura Paints, therefore other paints may not combine with the same outcome.
