That's probably a personal preference. You have your own preferences and of course that's your right and I'm not challenging your tastes but you have to know that you are of the minority opinion in finding most dark eyes significantly more dull/boring than light colored eyes. I'm not going to post pictures as counter examples because that's just silly but may I direct you to an extremely popular russian song (not a recent song, a folk song that is centuries old) about a man who is captivated by a woman with dark eyes.

Anyway, there are always colored contacts. What's the point of complimenting something so easily changed?
