When you travel, I always noticed that the blue is always just that bit stronger and brighter. It fills up the skies, the seas and makes for wonderful contrast against whatever is in the foreground.
Add a pinch of clouds and your eyes can widen in amazement at how Nature, even in this over-developed, over-populated world of ours, can still find ways to be amazingly beautiful.
I love the blue. Even if blue denotes contrasting meanings, it depends on how you see it. A glass half full or a glass half empty. Me several months back would have told you, blue is just another word for sadness.
I would be fracked if I thought that way ever again.
