So there's no some standard for colors for example if there is function
$mkcolor(154, 164, 232) (Some lighter blue) that everyone see color in that format.
I think that should be fine to add to mIRC, like ASCII is standard for any programming language as far as I know.
Example: I use ascii chars from mIRC when coding with PHP.
Also $ctime, it counts from 01/01/1970 00:00:00 in PHP also.
So I guess, now I can use only locally. Nothing for other users.
