I think I have one additional color - but I am missing one of yours. I have one that looks very Purple to me but isn't listed in the TCR and one that looks fuchsia to me and is listed. When I talked to Mr. Roulette at the convention in 2003 we concluded that there are 12 variation total counting the known "tight" and "spaced" letters.

I put a link to the eight different ones I have at the bottom.
