No, unfortunately you cannot insert color other than the ones the programmers have included within the game. if you use the GateKeeper program, i believe that you can switch up the characters colors to colors that are actually in the game (like using an armor hue for a character's hair color), but this discrepancy will cause the game to crash when you reload so it is not an option. just deal with the (rather limited) choice of colors for your characters. i don't know of any other alternative.
