Key Point: Bare
The last thing you want is a stand-out blush color. The goal is to underscore your cheeks, not color them. Skip the fuchsias and bright pinks and go with neutrals that are just a tad darker than your skin tone, like browns, bronzes or plums. Lighter skin can get away with a peach or pink.
In fact, the newest blush is no color at all; try a bronzer instead. The light shimmer will highlight your bone structure while blending right in with your skin tone.
Quick Tip: Before starting on your eyes, even and set the base by brushing a light layer of tone-appropriate (not too light!) translucent power over your foundation and blush.
You'll be switching gears when you head upward to your eyes.
