Paint by numbers

Like Yoggity, here's another game, Pastiche, that deals with combining paint colors to make various other colors.  It looks like you're laying tiles next to each other to generate the various colors you need to make masterpiece paintings - a neat idea; I don't know how it plays.  I don't think the games are very similar at all, but it's interesting to see somebody thinking partially along the same lines.  I haven't seen a lot of other games where you combine colors as a part of the gameplay.
