Can I be rainbow colored? Or maybe #e5e5e5? Or skin colored?
Rainbows totally aren't against the rules, I swear. Actually, while I was just joking about #e5e5e5, I could think of something pretty good to do with silver. Let me know if it's too close to gray.
EDIT: Derp, it is gray. I mean, let me know if it's too close to the other people who want to use gray.
EDIT 2: For that matter, people wishing to use the grayscale should probably specify shade.
