Borderlands 2 Getting a Colorblind Mode
More than a year after launch, Borderlands 2 will be receiving an update that adds a colorblind mode with three options. Only about ten percent of the population suffers from some form of colorblindness (or more accurately, "color vision deficiency"), so it's interesting to see Gearbox Software taking the time to patch a colorblind mode into the game so long after release (though the studio does continually produce content for the game).
Once the update goes live (no ETA at this time), players can select one of three types of color vision deficiency in the Video Options menu (Deuteranopia, Protanopia, or Tritanopia), or simply leave it off entirely. If you do happen to be colorblind, hopefully you know which form of colorblindness you suffer from, otherwise you can simply try each one until you find one that works best. Each mode changes the color scheme of items slightly to make it easier for colorblind players to distinguish between item rarity and type, in addition to adding a line of text enclosed in square brackets that states what color it is (eg. "[Green]" or "[Orange]"). This text is only shown if colorblind mode is enabled and examples can be seen below.
One last thing to note is that there was a bug discovered when colorblind mode was set to "protanopia" that was too late to fix for the upcoming update. Those suffering from protanomaly or protanopia are urged to use "deuteranopia" instead until the problem is fixed in a future update.
