Advice on what colors for this tattoo?

[LupeTheWolf]

So I have this new tattoo idea that I had my friend draw for me so I could get my exact concept down for my tattoo. It's a rearing zombie horse, and it'll be on my calf and I intend to have a full calf sleeve. Around the rest of it I want souls and smoke floating around and I plan for that to be black and grey.

But I'm curious if I should have the horse in color or black and grey? I really want this to stick out and be awesome. If it's in color, what colors should I choose? I think red, brown and green for the open wounds, grey for the hooves, grey for the mane and tail, and the skull be a cream-ish color.

Beyond being a zombie, are you wanting the horse to have any determinable characteristics... bay, palomino, Appaloosa, roan, buckskin, Arabian... color also tends to lead to type when it comes to horses.
