I don't see any reason why RGB would be limited to one color on the entire line in an /echo. It wouldn't be that difficult to make it possible to add any number of colors to a local /echo using RGB. Whether they are done using some RGB identifier or a switch that tells mIRC to treat all Ctrl-K's as RGB and parse them as RGB instead of the normal way... Ctrl-K255,35,124 or Ctrl-K255,35,124,40,87,237 for background colors or something like that (semicolon between would look better, but doesn't fit line up with normal color syntax). Or not use RGB in that way, but convert it so it's one number... Ctrl-K23578,54023 or whatever. The switch would just tell mIRC not to use only 1-2 numbers for the color code. There may be better methods as well. The point is that it shouldn't be difficult at all for local /echo to have many colors throughout a line using RGB, so there shouldn't be any limitation.
