Understand that a 'natural' look is one that uses colors that are right for your skin tone. Apply foundation that matches your skin tone. The right foundation will seem to disappear on your face. Apply eye makeup in earthy tones’ beige, brown, gold or plum for shadows and brown and charcoal gray for liner and mascara. Skip liner or shadow entirely if you want to keep makeup light. Choose a blush color that is close to the color of your cheeks after you've exercised.
