CVar gxColorBits

Sets the amount of Color Bits wow uses. Values range 16, 24, 32.

• 24

• 16 :16-bit color (High Color)
• 24 :24-bit color (True Color)
• 32 :32-bit color (Deep Color)

This CVar requires a UI reload. In-game, type the following /console gxDepthBits setting /console gxColorBits setting /console gxRestart

Alternatively, you can exit wow, open the Config.wtf file, and add the following line: SET gxDepthBits setting SET gxColorBits setting

As of 3.1, 16-bit is no longer a valid setting in the Interface dropdown menu. However, if you still need to use this setting due to a very low-end graphics card, you can via the in-game macro: /console gxDepthBits 16 /console gxColorBits 16 /console gxRestart Be aware that this setting does NOT save when you shut down the game, and you'll have to run these lines every time you log in.
