Natural lip color?

People are always asking me what shade of lip stick I use, but I don't wear any. I guess they are kinda pink, but this is normal right? Do people's natural lip color really vary that much?

Yes they look good

yaaa they do a lot. my little because whos like one has riiillly pink lips...its soo cute!
lol.

I don't know but I think it may have something to do with how healthy you are. Someone like yourself probably has a nice healthy color but someone that has vascular or circulation problems will probably have a darker purplish color. I bet that even dehydration would make a difference.
I feel the same way about hair. A healthy person will have soft, shiny, healthy hair but those who are ill or even aging, will have dry brittle hair and hair loss.
