Why do some people have red lips and others pink?

I always wondered...is it just genes or is it something we eat or do..like some guys and girls have these naturally bright pink lips and others have light pink lips..why!!!Why do some people have red lips and others pink?
The skin over ones lips is relatively thin (only 3 layers thick) as opposed to facial skin that is 16 layers thick. Too, lip skin contains no melanocyte (pigment cells which give skin its color) plus red blood vessels appear through this thin skin. That said, the lips of a fair-skin person appear a lighter red color than those, let's say, of a much darker-skin person. In exceedingly darker-skin people, you can see through the thin layers to darker tissue which contains more and more melanin.Why do some people have red lips and others pink?
Here are a few reasons for the difference:


1. Genes


2. Temperature: cold lips are not as rosy as warm ones


3. Anemia: If you are anemic from heavy periods, other blood loss, iron deficiency, etc., your lips will be a paler pink instead of red.
Genes I suppose.
genes blood flow i dont know i just know that i look like a coked out snow white after ive been out drinking really dark red lips and the rest of my face is pale except for the dark circles under my eyes
girls lips turn darker when they are sexually aroused or climaxing.
have you ever noticed that skin, hair and eyes (just to name a few), all come in a variety of colors and shades?
its gods gift to them
red are usually upstairs





pink are usually downstairs
Has to do with the amount of blood flow.
I like to wear lipstick and I am a guy.
