I logged onto minecraft this morning, and the color scheme was faulty. Black, white and gray background, red and green lighting. When I approach the lighting, it looks like the a 3D movie, without the glasses.
I don't know how to replicate this phenomenon, and all the settings were not changed.
Minecraft supports 3D. Works as intended.
You turned on 3d anaglyph in your settings.
Options > Settings > 3d anaglyph
