Forum poster Ardhavara has posted an excellent guide
to the color-blind accessibility mode for World of Warcraft
, complete with images of the various ways it helps different kinds of color blindness. The console settings for each type are listed, and there's a good explanation in the thread by poster Kaels
explaining each type and how these options help to make the game more distinct for each.
Not a lot of games, MMO or otherwise, work this hard to make accessibility improvements for conditions like color blindness. It's nice to see WoW
implementing something like this.
