According to color theory, if we want to hide skin discoloration, we should neutralize it with its direct opposite on the color wheel. This is why green concealers are best used to hide active acne or red spots, while peachy or yellow ones help conceal dark circles.
That said, the same rule should also apply when it comes to highlighting. Just play around with contrasting shades to make your skin tone pop!
If you have tanned skin with golden undertones like Chi Gibbs, a cool color like blue will make your warm tones shine even without highlighter. It's basically like color blocking but with your makeup! Incorporate it into your beauty look as an eyeliner like Chi did here, or go for blue mascara or lipstick.
