I play on PS4, and I am color-blind. I have the appropriate filter enabled, but the interface is still causing me issues because of what I can only assume are bugs. First, the health bars over monster’s heads are too subtle to distinguish the remaining health of monsters. Second, the immunity indicators are too small, and their colors too subtle, for me to identify a target’s immunities. The size of the indicator, in particular, is so small as to make me think the size value for the image is coded wrong.
I would love nothing more than to have the health bar at the top of the screen, from legacy, in addition to the overhead healthbar, and for the immunity indicators to be replaced by, or supplemented with, the original colored text declaring the immunity.
