I am trying to decide if I should be using a foundation with yellow or pink undertones? I think I have gone back and forth between the two. But now that I don't lay in the sun anymore it seems that the yellow based foundations make my skin look orangey. BUT I read that it is VERY rare for a caucasian to have pink undertones in their skin and that everyone should be using foundation with yellow undertone NOT pink. I have a sample home with me of four colors...2 with yellow undertones and 2 with pink undertones. I think the one that looks best on me is one of the ones with pink undetones...it looks natural. BUT is that possible? Why do make-up artists say that everyone should be using make up with yellow undertones? THANKS!
