When I first signed on to this site a few years ago, there were at least two color-themed challenges. I remember, in particular, one was a color-combo challenge and there was also a monochromatic one. Did they end because the hosts got tired of running them, or was the level of interest too low?
I'm asking because I'm thinking that a color-related challenge would be easy to apply to all kinds of projects. Would there be any interest in something like that, do you think?
