Fives across the board for me, as I love to think about the fact that people build and swim in pools right next to the ocean. I suppose clorine over salt is a choice some end up making. Anyway, great concept with the colors, thanks for posting!

this almost feels like two different photos stitched together. i think it would have been a stronger composition had the split between the two colours not been dead center.

Ooh, freaky colours.

In terms of processing technique it's a very clever shot, but I don't think it adds much to the overall impact. I like the clouds, they look dramatic.
