Blue is my favourite colour. Nature’s beauty is at its best in the form of blue sky and blue waters. Beautiful is the word I would associate with blue. Yet I have always wondered why blue is also used to mean gloomy, depressed, sadness, etc. Though the answer was always just a Google search away 😛 , thanks to sheer laziness on my part, I finally found the answer only today. In case you are interested in knowing it, assuming of course, you don’t already know it, here is what wikipedia says:
In the English language, blue may refer to the feeling of sadness. “He was feeling blue”. This is because blue was related to rain, or storms, and in Greek mythology, the god Zeus would make rain when he was sad (crying), and a storm when he was angry. Kyanos was a name used in Ancient Greek to refer to dark blue tile (in English it means blue-green or cyan). The phrase “feeling blue” is linked also to a custom among many old deepwater sailing ships. If the ship lost the captain or any of the officers during its voyage, she would fly blue flags and have a blue band painted along her entire hull when returning to home port.
