I already did, see? [link]
I always submit the colored one right after the stats page..
but yes, please do color it! Just use that one as a guide, and make it any color you like! ^_^
I'd just strongly suggest you keep the eyes the same color, and It'd be best if you keep the color -pattern- the same (turn all the gold parts blue, all the brown parts red, etc)..
but you don't have to.. I'd just be stoked if someone colored their own DC :3
