There’s only a million of these out there, but none that I have found were consolidated into one post, were too vague, were overly complex, etc., etc., etc. I’ve made my own post of colors of import.
I’ve probably missed stuff. Send me an ask if I have, or if something is horribly wrong. If something doesn’t match what you have in your head or MSPARP or anything, let me know! I want this to be as accurate and updated as possible. Hopefully someone finds this helpful. ^^
EDIT [8/9/14]: Fixed some stuff, added Autoresponder.
