What Color Is Blue?

Yet another lovely day at the beach. A later start than usual, the day was so warm it was not comfortable until after 6pm. And once we arrived we chatted for another hour before entering the water. The sun was just dipping below the horizon as we swam. I finished a bit before Laura, and wandered the nearby beach. I came across this array of blue chairs, and the variety of blues prompted thoughts about the nature of color, not only as we experience it, but as it translates to photography and ultimately onto the computer screen.
