In picking a color, let nature be your guide: The trick is to choose a shade that matches the color of your face when it’s flushed from exercise or cold weather.For a quick check, slap your cheeks a few times, see what color you get, and then choose a matching color. Another method is to match the blush to the color of your lips. General tip: Fair skin goes well with rose; olive skin with peach; and dark skin with apricot or red.
