If you're attractive eye color won't matter much unless we're talking very dark brown, almost black eyes on a white guy. It just looks off, but it doesn't necessarily matter as much as most people think.
If you're attractive you can get away with any eye color, but blue, green and grey generally compliments white Chads well. There are white Chads with hazel and brown eyes of course.
For mixed non-whites (example: most blacks in the US are mixed with white), light eyes are rare and exotic looking, especially if blue. It can give you maybe a full point at best. Light eyes are definitely a bigger advantage if you're non-white.
