Follow the perfect directions that Venus gave you. Don't expect a "perfect" color match, however. Your skin is not always the same color. As you might expect -- look at the color of your RL skin -- the color depends on the time of day, the sun angle, whether you are in shade or direct sunlight, the color of other lights around you, and whatever Windlight settings may be used where you are standing. The best you can expect is a rough approximation of your skin color that will look "sort of correct" most of the time.
