Well, this is a good question. Men differ in their preferences when it comes to their favor of eye colors on women. I am a dude, so I will definitely go with crystal clear blue eyes. They really look fascinating and mesmerizing. A sight of such colored eyes will render me infatuatedly paralyzed. (Shame that my girlfriend doesn't have such amazing eye colors, lol. But I love her anyway.) Many of my friends around me find green attractive, especially on girls with dark brown or black hairs. Some others are into hazel or black color. Eye color is just a facet of women's attractiveness, so don't bother yourself with it. Any color matters as long as you exude confidence when with guys.
