I was hunting Nessos for a turle shell this morning using CRZ. I found out that if you get affected by Vicious Rend which is an ability of Saurok rares in Pandaria, you bleed red and such. If you zone back to your server while affected the debuff will come off but you will still be red. I have yet to confirm if this is server or client side but either way it looks awesome. Persists through loading screens but not logout.
