This 1 Trick Will Ensure You Never Wear the Wrong Lipstick Again

Blue-based reds are a popular color suggestion for women with cool undertones like Emma Stone, but don't limit yourself to carmines! Craig-Ryan French, artistic beauty director and global makeup artist for Paul & Joe Beauté, points out that pinks with hints of blue work well, as do hues like magenta and jewel hues, which also tend to have a cyan cast. “Reds, wines, and berries contrast nicely with cool undertones,” King notes. Kashuk explains that this works because of the blue undertone in both your complexion and the lip formulas. "You are matching to color tones — it’s all about coordinating the colors."
