- Emphasis: Color theory can be used to bring out your best colorful feature — your eyes. When you arrange two colors from the opposite side of the wheel next to each other, it makes them both pop. So blue-eyed beauties should look to orange and golden-toned shadows and liners. Green-eyed girls look to purple or rosy shades for an extra bright look. And for the brown-eyed babes, practically every color can work for you.
- Corrections: If you're looking to reduce the appearance of a mark, dark spot, or pimple, turn to a colored primer or concealer to balance out the area. So, if you're attempting to shade in visible blue under-eye veins, reach for an orange concealer. Have rosacea or a red-toned pimple? Dab on a bit of green primer to erase it. Just remember: put an unwanted color in its place by looking to the opposite side of the wheel to find its balancing match.
