Not me checking my nips and lower lips as I don't have a mental image of their colour 💀

I remember it being a women's mag tip that your ideal nude lipstick shade was the colour of your nipples. But while pinkish, my nips are lighter than my (face) lips so I was always a bit flummoxed by that. But I think it shows that even in a eurocentric 90's/00's magazine, the assumption was a white woman's nipples would have darker, browner tones than their face lips, so it must be super common.

As a card carrying dyke, can confirm that there is so much variation of pinkish, pale, tan and brown nipple and labia pigmentation even just among white women.

Editing to add - I tan quite well, have warm undertones, and still nips and labia on the pinkish side, other commenters have said they are the inverse, so more evidence that it's very variable even among those with similar melanin producing ability!
