Blizzard has finally added in the promised colorblind support for World of Warcraft.
This is how Blizzard explained the game’s new support systems:
For example, when you move your mouse cursor over a piece of rare gear and then a piece of epic gear, the game colors the names of the items blue and then purple, respectively. With ‘UI Colorblind Mode’ enabled, the game will add the words “Rare” and “Epic” to the tooltips for those items. For players who find it difficult to discern between friendly, neutral, or hostile targets, additional indication text in the tooltip will now appear when you move your mouse cursor over other characters.
