Agreed. I'm also red green colour blind and at the best of times it's hard to see. If you're standing inside a support station, which is a green highlight, and the aoe is targeted on top of it, good look trying to see it.
I'm not colorblind and it's hard to see. Can't imagine how even harder to see for those with colorblind.
Normally it's easy to see but when in action, it can be hard to see. Especially when got "disturbed" with debuff that changes the screen color.
Btw Changing character's jacket and shirt color to white also helps.
