The shuffle variant is a holdover from the versions on which the mod is based (iChadiumMod, iChadium, and iChat Clone.) Shuffle cannot work because CSS doesn't allow for a color to be selected at random; such a selection requires another program written in a language beyond my capabilities. If anyone knows how to write and implement such a feature, I'd love to add it to the mod.
