I had the Color Blends green- the picture on the site doesn't do it justice because you can't see the subtle shades of the browns and greens blended but it's a nice color.
Thye have added, like, 10 colors since I've used those contacts so maybe the size of the lenses have changed but they were quite a bit bigger and thicker than a regular contact, just to let ya know!
Oh yeah, my natural eye color is dark brown- almost black, and the contact looked pretty decent, just to give you an idea of the color payoff.
