It looks like the pairings for what forms will go with what hair colors are up on the WoW forums and MMO-champion.
The Forum post has a list of the combos. There are sets for tauren male/female, and Night Elf male/female. The Taurens get some actual mixing & matching of the feral colors. The NE’s have pretty much a 1 cat to 1 bear pairing (NE’s do have less hair color options than Tauren have skin tones). Tauren male have 7, tauren female have 6, and both NE races have 5.
Then, MMO-champion did a great job of actually turning them into pictures so that I don’t have to paste the giant block of text here.
So, which Night Elf cat/bear pairings to I like the best? Well, I’d like the dark blue pairing, except that they put pink dangly balls on it, which prompted all of Big Bear Butt’s ball jokes. There is also someone else who photoshopped the cat forms to look bejeweled. Personally, I’m not likely going to want to run around as the white cat, as the pink cotton-candy fuzz is just not okay for me. The third option still has a lot of pinks & purples, so while I like the bear, I’d rather go with something less bright day-glow for my cat form. The fourth one is actually my bright green/blue hair color, and has the more subtle purple & gray colorings that I may just stick with my current hair color and keep those graphics. The 5th one has my favorite cat paired to my least favorite bear, so I probably won’t go with that pairing. I really, really need to see ‘em in action before I decide. Looks like I’m going to have to download the PTR this time around.
You should be able to click on the pictures to go to the larger size. Here’s the Tauren pairings, which I love all of them (instead of spending time deciding which pairing I dislike the least, I’m trying to decide which one I like the most). It’s definitely time for me to go back and re-dedicate to leveling my Tauren druid as feral. I’m thinking the bottom right one (the dark gray bear paired with the white cat) actually looks pretty interesting, but it’s male-only. For my female one, I’m probably going with the white/white (very bottom), or maybe the brown/brown the third down on the left.
What colors will you pick?
