Blue is a color, the perception of which is evoked by light having a spectrum dominated by energy with a wavelength of roughly 440-490 nm. It is considered one of the additive primary colours.
On the HSV Color Wheel, the complement of blue is yellow; that is, a colour corresponding to an equal mixture of red and green light. On a color wheel based on traditional colour theory (RYB), the complementary colour to blue is considered to be orange (based on the Munsell color wheel).
The English language commonly uses "blue" to refer to any colour from navy blue to cyan. The word itself is derived from the Old French word bleu.
The modern English word blue comes from the Middle English, bleu or blwe, which came from an Old French word bleu of Germanic origin (Frankish or possibly Old High German blao, "shining"). Bleu replaced Old English blaw.
The root of these variations was the Proto-Germanic blaewaz, which was also the root of the Old Norse word bla and the modern Icelandic blar, and the Scandinavian word bla, but it can refer to other colors.
A Scots and Scottish English word for "blue-grey" is blae, from the Middle English bla ("dark blue," from the Old English blood). Ancient Greek lacked a word for color blue and Homer called the color of the sea "wine dark", except that the word kyanos (cyan) was used for dark blue enamel.
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.
Many languages do not have separate terms for blue and or green, instead using a cover term for both (when the issue is discussed in linguistics, this cover term is sometimes called grue in English). Blue is commonly used on internet browsers to colour a link that has not been clicked; when a link has been clicked it changes yellow or orange or purple.
