What the hell are you talking about.
echo("\c0\\c0 \c1\\c1 \c2\\c2 \c3\\c3 \c4\\c4 \c5\\c5 \c6\\c6");
Doesn't it go all the way up to \c8 or something?
EDIT: It only goes up to \c5 in the console, but goes up to \c8 in-game.
In-game the colors are as follows: c0 = red, c1 = blue, c2 = green, c3 = yellow, c4 = teal, c5 = purple, c6 = white, c7 = gray, c8 = black.
