Shades of blue

I have a busy work week and am traveling soon but after that we will return to Mexico. How many shades of blue can you see in the photograph? The blue green of the Caribbean is so lovely contrasted against the blue sky. This is the pier at Celestun, Mexico on a windy but warm day. There is no one on the beach behind me – a little piece of heaven. Despite my last post, my mood is not blue just reflective.
