Of course it's not.
The only thing I'd even consider close to being inappropriate in someway, is to describe the color of someone for no reason.
But even that's a stretch.
Like "So this black kid tripped..." Just because it has nothing to do with anything.
When I was in class one day, in a mostly white community, we had one black girl in our class. She was real cool, and we worked on a project together as we had a few classes together and always hung out in between classes.
We were both from racially diverse communities, and not from the area the school was in so I think we got along because of that as we were both really comfortable with each other.
Anyways, I could never remember her name, because we'd always address each other in a "hey you!" playful manner, and one day she was out, and the professor asked who was my partner for the project and I said something along the lines of... "I'm working with, ahh I always forget her name, the black girl." And everybody stopped like I said something offensive.
So during the brief bit of silence I said "Yea you know, the only black girl in class."
And it took me a minute to realize I had thrown a lot of people off just by saying that.
And that's just ridiculous.
