I used amber for stream and stillwater fishing. I can't comment on what heps in the salt.

I have a pair that I can change the lenses in, so I used to use grey for driving and amber for fishing. I found I like amber more for everything now. Works great in snow and rain, too. I never use my yellow lenses, but I am sure there will be a day when they work for something. So if I had only one choice, Amber would be my color.
