Hello Amigo. This must be the island of the multi-toned blues... even the fine perspective leads the viewer's eyes to a structure on the horizon which is.... blue. And of course, this well composed photo is unified by a nicely exposed sky of.... blue. I wonder, on this picturesque island, if the natives ever sing the verses to the famous Frank Sinatra song:
"Blue, blue, my world is blue
Blue is my world now I'm without you"
Ciao, Michael
