There are five ways to type in color during a game(at least that I know). Here are the colors and there codes.
White-..........no duh............
Black- Hit <color> then a space and your message. (Can be done in the middle of a sentence)Red- Hit <color=9,0,0>Blue-<color=0,9,0>Green-<color=0,0,9>Note: You can type several colors in one sentence. it takes lots of time, but you can do it.
Note: I may of gotten the blue and green mixed up. I'll edit it if I find out it's wrong.
If anyone knows how to put pictures in your message, post it here as well.
Hope this is fun and helpful
Final note- This is in the game, not on AOMH forums.
