They sorta had their regular run colors with the brushed patches (blue, green, amber, light blue, clear) and some of the comets came in regular color combos, but I agree, the higher percentage of Masters found seem to be a fairly random mix of colors instead of anything predictable. I wonder if they just threw whatever color they had convenient in the tanks and let 'er rip? You do see an awful lot of sea green and brown together on them. Anyway, here are some I recently got around to photographing. One with AV in a strip, and one with rare Master oxblood.
Dang, I can't make them show up here for some reason... lemme see if I can fix it.
