Adding my support to this thread as someone who has been pretty active in the Eye Strain thread since DT started. Accessibility is the worst it's ever been and many people have been trying to point that out for months now to no avail. I don't have colorblindness so I can't speak to those issues, but this is something a major developer publishing one of the biggest MMOs should be aware of. There should be more options available to deal with these issues.

These visual elements are a way for the devs to flex the capabilities of the updated graphics engine, which is why it's a recurring problem in DT content (even though examples date as far back as SHB). Looking pretty doesn't mean much if it's indecipherable to people trying to play the content, and it means even less when it's causing harm to players just trying to play the game. It's a design philosophy they need to reassess.
