Adding support here. Even as someone without colorblindness or photosensitivity (but getting older), it's getting very hard to read with low contrasts, similar colors, and lots of flashing. I already have other player effects limited or off and it barely helps. My friends who do have visual impairments or other disabilities are definitely having issues. When a person I know can't even try a new job because the common advice of "if this color, go flank, if that color, go rear" does nothing for them!

SE is far behind the curve in accessibility options as it is, and continuing to make fights like this (after numerous issues concerning difficult visuals, often for the exact same reasons in previous expansions!) shows a disturbing lack of concern on the part of the encounter and UI developers until it's once again pointed out and they're forced to change it. Though some instances, unfortunately, are never updated (P3's orange on orange on orange, for example).
