Prisma 24 Color Matching Guide

This is a simple hand-made color-matching guide for the Prisma 24-piece (23+black) marker set. The colors that touch directly I have determined to be the colors that "match" (i.e. can be used as alternates in 2-tone, or 3-tone where possible, cartoon shading). All of the colors are here. Hopefully someone will find it useful--I know I will! ...Please comment if you feel I overlooked any matches or made any matching mistakes...
