There's not nearly enough colors here. Maybe a custom colors option or using "#000000" tags? Or is there already a way to expand these? If there is, I haven't been able to find it...

it uses the 16 colors defined by mIRC

if you want other colors, just redefine some you never use *G*

I'ts not that there's anything wrong with the colors, it's that there's only 16. There aren't any I don't use, that's the problem.
