It is really impossible to list all colors.
Colors are stored as 3 2-char hex values [from 00 - 0 to FF - 255], in RGB order [first value defines red, second green and last blue], plus 2-char hex value descripting transparency, so standard color code looks like:
|c00ffffff|r
Syntax:
|c - defines start of color definition
00 - 2-char hex value [0 - 0, 1 - 1... etc. A - 10, B - 11... etc. F - 15, FF - 255 [max]] descripting transparency
ff - same as above, destripting red color
ff - same as above, but green
ff - same as with transparency, but blue
|r - end of color definition
All colors set to 00 gives black, all colors set to FF gives white. 00FF00 gives green and FFFF00 gives yellow. But I strongly suggest to use any of color managers, as they are easy in use.
