Grey-blue when looking through them. Very soothing to the eyes. Great optics as always with Oakley. Can wear this all day without any fatigue. No reflections or halo.

Edit: when I wrote this review I had owned the ice lens for a few years but hadn't experienced the glory that are other Oakley lenses. Now that I have, I must admit that there are quite a few lens options that are more exciting than Ice so I decreased its rating from 5 to 3
