Black and Gray. My back Tats are all black and gray. I'll post a pic of my Back tattoo to show what I currently have. I've been looking for a proper drawing of that skeleton angel for over 3 years now. I'm gonna scrape whatever cash i can get together and get these done a.s.a.p... The basic theme all along has been good side bad side. The left side of my body's tattooed images of Satan, and Death. The right side is an Angel, and a Colored sleeve(when it's finished), and a tribute to my wife and kids. The Ying Yang with the Cobras in it, in the middle of my black represents the struggle between the 2. I have a tribal cynical face below that, and a Brazillian Pentagram at the bottom of my back. The Angel skeletons will go on each side of my mid to lower back. I'll post a pic once I'm done uploading it to Photobucket.
EDIT:

It's a bit blurry, but you can see how it narrows. I'm gonna fill those areas in.
