Hello! Apologize in advance for my poor English, but I hope you’ll understand me.
Currently targets hitpoints, shield, armor, structure displayed by only red color being damaged. Sometimes when you play on armor rep logi and your mates armor starts leaking when it’s shields was nearly fully damaged before, you just don’t give attention because both shield and armor color merging with each other. I just suggest to add simple menu where player can override basic “red color” scheme by his own, selecting colors for each hitpoints types at his discretion. That’s all.
Here is just little example of how it should look. Sorry, bad at photoshop ¯_(ツ)_/¯
