Unless there's a DLL that does that, you can't. You can change the RGB color of each of the 16 colors by right clicking the square in the colors dialog or by the /color command.
yea i was thinking that might be possible, writing a new color to the mirc.ini for one of the 16 slots, then use this slot for my echos?
problem is, the colors are in user text messages which i strip out from the on text event
so every time a user types something, i have to use the /color command and echo using that slot?
