How to pick a red lipstick for your skin
Undertone, depth and a daylight swatch.

Skip the rule books. Swatch two reds on your inner arm in daylight and look at which one makes your skin look warmer and brighter. Blue-leaning reds suit cool undertones, orange-leaning reds suit warm ones, and most people can wear either.
Blot for comfort
Press a tissue on the lips after the first coat for a softer edge and longer wear.
