im interested in custom lenses, In my car 99 civic, the rio is in a direct sunlight for most of the daylight. I would like to know which colors would provide the best visibility in sunlight.

If you wait about a week or so, I'll hopefully have Darkstorm's lenses added to my lens comparison chart and you can decide for yourself.

Personally, I anticipate the Smoke and Clear lenses will equal or exceed the green lens pictured there.
