Fun eye make-up for blue eyes. The blue from the eye shadow will clash with your brown eyes causing them to pop. Another idea is to use a blue eyeliner instead of the blue eyeshadow for a more wearable day time look.
Maybe it's just my skin tone, but I have found that pink eye shadow, (Or beige or caramel or anything from that color family,) looks amazing on my eye. It isn't so much that it makes me eye color pop, but it makes my skin glow.
