Customizeable colors for map overlays and other game elements

I play FFXIV with a friend who is red/green color blind, and FFXIV's map is very difficult for him to see in general, but the orange and green overlays are particularly bad. Please allow those colors to be customized, along with colors for the attack area on the ground (red on green grass is nearly impossible to distinguish). UI elements, especially important ones that affect gameplay need to be color customizable to make the game more accessible.

I agree! While I do have good vision it does get rather difficult to see the light orange aoe circles/cones. It gets especially difficult in coerthas or when the ground is yellow like sand.

There should be a feature to atleast increase or decrease the transparency
