Hahaha wth, I think I've seen you on youtube before.
Or... am I just putting random things into my head? Either way, it makes me feel like a creeper.
Anyway, I think your natural brown eyes would look best with your current hair/skin tone, but if you were to get colored contacts, I'd say green. Green would also look good with your hair/skin tone, and I feel like it'd be the most natural-looking option as opposed to something like... blue. That just screams fake. Just be sure that the green isn't too bright or unnatural, unless that's the look you were going for, haha. Some people get colored contacts because they like that extreme look, but in the end it really just depends on what you want.
