I have Deuteranopia. It's not that common, but it's not uncommon either.
With each update to the graphics, it's getting harder and harder to see. I've been completely disinterested lately in playing. The old graphics engine with the useless night vision, but very useful heat vision, was perfect for me. It sucked having to see everything in only blue but at least I could make out enemies.
Now, all vision modes make it difficult to see. The green/yellow filter used on everything in Caustic is getting ridiculous. The yellow haze in the lower city (7 line one) in River city is bad as well. If I knew that it wasn't on purpose, I might be offended.
The difference in the armor status hud screen is really bad as well. I have no idea from orange to green (save the nominal green) how my armor or internals are doing.
Please Devs, think of accessibility sooner rather then later.
