Last summer I found a distinct light blue that was glinting in the sun out on a sandbar during low tide. People near were oblivious and I paused briefly to enjoy the moment before walking 15 feet to pick it up.
Something else I just remembered: I was walking along the shore looking down. When I finally looked up, I saw that I was out a long distance on a sandbar. That's when I saw the light blue sea glass.
Walked a long distance back because I had my iPhone. Happily walked a long distance back, I might add. :)
