More distinctive color usage in characters

In recent years many new chacraters appeared that did not comply with the "standard" color scheme of the game. It is giving me hard times, beacuse I can not decide wich skin belongs to wich team anymore. Earlier the skins were clearly GR or BL, with blue/black and orange/red/white colors respectively.
But now a female character in pink is in the GR team, and another with mostly black (with very little red in the front) is on the BL team. A guy roaming around in a labcoat can be GR and BL too.
I know, I can hover my mouse over it, and it will dipslay the name with the correct color, but it should be a thing that can be easily determined.

(To put it in a more scientific perspective in the UI/UX design there is a principle called familiarity. This principle is being violated by these characters)
