you are still not getting my idea (is my english so bad?)
"will not be extend cuz of the "other clients"... buuuuuuuuut why cant you make a /Xline using rgb colors?"
i meant, the 16 colors will not be extended... JUST THIS, forget the rest :P
i just want to /aline, /cline, etc, with rgb... no other client will see []934876 because I WILL NOT SEND THIS... it will just change the way "textboxes" (or just "listboxes") display the text... instead of use a palette of 16 colors, it uses a 16bit... irc will interpret []4 like [](255,0,0) for an example, but just client side... so you can make /echo [](50,100,150)text...
the [] could be another character...
or make this just for lists... so there is no [](1,2,3)... and i dont know how the mirc listbox works, but i suppose that it dont uses [], so i think its easier
PS: substitute the "will"s on the text for "would"s :P
