Is this normal??? Weird question sorry

I have always read that your labia/vagina is supposed to be a nice pink color. For the most part, mine is pretty pink. But I noticed in like different lighting (or if I took a picture with flash (don't ask)) it comes off as a more purple color.

I know for sure I'm not pregnant (negative blood test, haven't had sex in three months, have Nexplanon)

So is this normal? Can your lady bits be darker than pink? Or is something wrong?
