What I expected to happen was to tame wolves, acctually i can tame wolves normally, but there is a problem.
The collar should be red coloured

But what actually happened was that the collar was orange, and every wolf i tame spawns with an orange collar. then i dyed one with a purple dye and it changes color "normally", then i decide to switch to the 1.7.10 and actually what happens is that the wolves have the red collar, and not orange, and the one i dyed purple changed to green, so i think what is happening is something similar to the wool wrong colors with sheeps and names in the debug screen, etc.

Steps to Reproduce:
1. Find a wolf in survival or spawn in creative, it really doesn´t matter
2. Use a bone to tame it normally
3. You can see that the collar is orange at turning and not red, you can dye the collar with the respective dye and it will change to the "correct" dye, if i take bone meal it turns white, if i take purple it turns purple anyways.
4. If you switch to a 1.7.x version you see that the orange ones turned into red ones, and any other dyed color also turned to other diferent color, you can return to a 1.8 snapshot and see that the red ones turn to oranges again, you can keep switching versions and the colors keep switching the same way.
