The color of the dog has nothing to do with it's lifespan. (not quite sure why that was added). But pitbulls live about 9-12 years. Although Ive known some pits to live until 14 years old, thats a little more rare, but still not too uncommon.
9-12 years
Ive heard everything from 9-12 years to 13-15 years.
I think the life span varies.. I've heard that they have a week immune system that causes the short life span.. But so far I've had my blue bit for 2 years now.. He has allergies but nothing serious...
Hope that helps!!
