So, id love there to be a system where we can customize our own unit color schemes.
Yeah some stuff might look similar, but id refer you to a 1995 game called Open RA, where their color schemes make you change to an alternative if your color is too close to another players color in the game.
(come on if they could do it 17 years ago, they can do it now...).
pleaaaaaase 
Also noticed that the current colors are not entirely accurate to how they appear on the units themselves.
