We have the translucent colors of: red, orange, yellow, green, blue, purple, clear, and light blue We have the opaque colors of: black, grey, and white If we assume that white = clear, translated from opaque to translucent. Then we need a dark smoky for black, and a lighter smokey for grey. Red, orange, yellow, green, blue, and purple all need opaque versions. However we are still missing brown, in the entire spectrum of colors. I think a smoky brown (wasn't there a discussion of rootbeer colored pyramids a while back?) would be a nice translucent, as well as a nice simple brown for opaque. I would get the basic colors done in opaque and translucent first before I went on to other colors. Basic colors being the spectrum of red, orange, yellow, green, blue, and purple; with all the non-rainbow combination colors black, grey, white, and brown. Thanks Fred Poutre Cloven Fruit Games
