The trouble is that different people have difficulty with different colours. I my self am colourimpaired with "Anomalous trichromacy" with greens/yellows reds/browns and a whole ton of other colors get distorted in certain lights or conditions. i sometimes find i cannot distinguish pale colors and whites. i often said to friends t hat i'd never seen a red orb once but apparantly its such a pale shade of red its hard for me to see.

i do agree that games in general should have customization options for colorblind players. number of games i have difficulty with stuff at range cos i cant see where the red dot of my laser sight is or what ever. which is one reason i tend to like sniper rifles even as a close combat weapon but a simple option to make my laser sight blue or green or any color i want would help a lot.

in more generic terms of final fantasy in xi i had trouble with some of the enms because the're be an orb and the color of that that orb was its elelmental weakness or something similar. and for me that was a nightmare as ice,water and thunder all looked the same so did wind and earth. so hopefully i never encounter this kind of thing in xiv. or if i do it has some kinda of option that helps people with difficulty and colours. perhaps a simple option to add a w y r tag to the orb when crafting to distinguish its color or something.
