Curious on other people's experiences on this since it seems off to me...

I have Green hair so according to http://forums.worldofwarcraft.com/thread.html?topicId=17631614423&sid=1&pageNo=1

I should have the violet/green mane bear(bottom left) and blue cat(top right) however I have the black bear with a white mane.. (cat is correct though).

So.. anyone else noticing this?

It was a bug. As Bornakk posted in the PTR forum earlier, it's been fixed internally and should be up on the PTR soon.

The green hair colors will correctly correspond to the violet, green-maned bear then.
