Here's the story behind this one: I was in 6th grade when I started to notice my brother's good friend. [ my brother is a few years older than me ]. I was always kind of attracted to older boys, but he just attracted me the most. I was walking with some people when I just blurted out I had really liked Manny's pretty hazel eyes [ the boy's name ]. From that point, I liked him for 2 1/2 years lol Just little things he did, like walk me home when my brother didn't want to, or talk to me about random stuff. I even remember a time when we were alone together in the basement because my brother was getting ready to go out with him, so he made himself at home [ he was close with my mom as well so there wasn't any problems. ] I was playing an online game when he sat next to me making fun of me. I guess we flirted a bit because the next thing I knew, I was was looking straight into his eyes...I love that moment, but no first kiss came outta it...boo. lol
Green. But that's just me being biased, because I have green eyes and I realize that they're less common. Less common tends to appeal to me, no matter what the subject. =P
Generally though, I don't have a real favorite, because beautiful eyes come in every color. I've seen the usual favorite 'baby blues' be plain and boring on more than one occasion. The color is nice, but there was nothing special about the eyes as a whole to make them stand out. Other times, I've seen beautiful brown eyes glittering in the sun, and it almost took my breath away. Or eyes so dark brown that they're nearly black, but that appealed to me because they were so amazingly expressive. That's attractive.
It always varies for me. I'm pretty impulsive as a rule, so my 'favorite' is usually whatever last REALLY caught my eye, and will be different after my attention has been drawn to something else. =P
Oddly enough I love every eye color except brown. Scientifically speaking brown is considered the most attractive because it reminds us of pupil dilation which is associated with returning affection. However, brown eyes simply reminds me of my past bullies and bad doctors.
