When enabled via the Video Options menu, the mode will display the name of the colour of each item via text on its stats card, programmer Jeffrey Broome said on the developer’s blog.
All items will have this line of text when colorblind mode is enabled, including items dropped in the world, items found in a chest or vending machine, and items in the player inventory.
Players will be able to select from the three types of colour vision deficiency (Deuteranopia, Protanopia, or Tritanopia) or select “Off” to turn colour-blind mode off.
“If you aren’t sure which type of colour vision deficiency you have, you can just try them out one by one until you find the one that works best for you,” wrote Broome.
The programmer noted that Protanopia mode will carry a small bug when the patch is released, which will cause red and green to show up as very similar for protanopes.
“This bug was detected too late to change it in the update so it will have to be fixed in a future update (it can’t be “hot fixed”). For now, people with protanomaly or protanopia should just use the ‘deuteranopia’ colour-blind setting instead.”
