In a recent thread, the OP requested that his white shirt be changed to maroon. I looked up "maroon" in a few websites and there appears to be a consensus that it's defined as Hex Code 800000 and RGB (128,0,0). Sounds good to me, so that's what I used. But I'm wondering if there is a standard listing of color specifications that most graphics professionals agree on?
Here's a website that lists the definitions of dozens of named colors, but I don't know how authoritative this is.
