I loaded Minecraft with 3D anaglyph on. I loaded a world, and when i turned 3D off, I (my minecraft player) was black and white.

Note: You must load minecraft with 3D anaglyph already on. Otherwise, it
won't reproduce. (see steps to reproduce)

What I expected to happen was...:
The player would be normally colored when switching to normal, as if you never switched to 3D

What actually happened was...:
The player was black and white, like in a silent film...

Steps to Reproduce: (very important!)
1. Load Minecraft
2. Switch to 3D anaglyph, then save and quit.
3. Reload Minecraft, make sure 3D anaglyph is on when you load
4. Load a world, any gamemode
5. Press Esc, and go to Options -> Video Settings, and turn 3D anaglyph off.
6. Exit pause menu, and inspect player.
