Depends on the person.
Xenon, if a white person would say that to you in a friendly-type of gesture, would you accept it?
If it's someone I just met, I would be offended. If it's someone I know well, and it's like him to joke around a lot, I wouldn't mind too much.
Nonetheless, I'm still uncomfortable being referred to by the color of my skin, unless it's used as a description for easy identification. I'll say "Look at that black guy over there, doesn't he have a funny hat?" But I won't say, "Hey, black guy, look over here!"
