I wouldn't, personally, because I'm mostly satisfied with the one I have now. In my own opinion, I think people need to start coming up with more themes for their colorsets, instead of just throwing them out there as "Colorsets". For example, there was one that was entirely monochrome, and recently on RTB I saw some colorset that was all dark, bolds, made for DMs or something. Things like that. I think it makes people more likely to download your colorset if you actually tell them what it's useful for.
