I was playing around with dyed leather armor for a PvP map I was making. I used the "/give @p leather_chestplate 1 0 {display:{color:0}}" and put the black chestplate on.

So I hit the F5 button to see how good the custom 0 ID color looked like when I noticed the sky had some sort of large rectangle in it and everything that was aligned with it had it's color inverted.

I also tested this with other color IDs and by manually dyeing the armor. The same bug occurs.

Steps to Reproduce:
1a. Put a crafting table down.
2a. Dye a leather chestplate any color.
3a. go to step 5 unless you want to use the command block method.

5. Put the armor on.
6. Press the F5 key.
7. Look downwards with the sky in the background.
