Work with What You Have
The best way to find a lip color that will enhance your natural skin tone and lip color is to wear a lipstick that is only a shade or two lighter or darker than your natural lip color. You can do this by applying lipstick shades to only one half of your lips, either your top lip or your bottom. Then examine the way the color looks in the mirror to determine whether it is just a few shades off from your natural color. You could also place the lip color on the skin just above or below your lips to see how well it blends in with your lips, just remember that skin color is a completely different shade than lip color, so it may appear lighter on your skin than it would on your lips.
