- Don't be afraid to throw it all out the window: "Back in the day they used to say, 'If you're a warm only wear warm colors; if you're a cool, only wear cool colors,'" McCarthy says. But, she recommends throwing that whole notion out the door. While McCarthy notes that she does look at her clients' skin tones to choose their blush colors, she also looks at their personalities: "In the end, it makes people step outside the box to kind of really see what makes them feel good about themselves."
- Think brightening, but natural: "For someone with more olive skin, peach tones look really good, and they tend to brighten the complexion, since yellow or olive skin can sometimes look a little sallow," McCarthy advises. If you're more fair-skinned, consider yourself lucky; you can get away with wearing just about any color. "And for darker complexions, I really love deeper plum tones and deeper pinks — and even a straight red blush would be gorgeous, as well."
- And for something that works for everyone: For a universally flattering color, McCarthy recommends Glo Minerals' blush in Sweet ($26). "It's similar to Nars Orgasm," she explains. "It's a really nice metallic peach with a pink undertone, and it works on any skin tone."
