Blue is a colour, 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 Colour Wheel, the complement of blue is yellow; that is, a colour corresponding to an equal mixture of red and green light. On a colour wheel based on traditional colour theory (RYB), the complementary colour to blue is considered to be orange (based on the Munsell colour wheel).[2]
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.
Etymology and definitions
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 blæwaz, which was also the root of the Old Norse word bla and the modern Icelandic blár, and the Scandinavian word blå, but it can refer to other colours. A Scots and Scottish English word for "blue-grey" is blae, from the Middle English bla ("dark blue," from the Old English blæd). Ancient Greek lacked a word for colour blue and Homer called the colour of the sea "wine dark", except that the word kyanos (cyan) was used for dark blue enamel.
As a curiosity, blue is thought to be cognate with blond, blank and black through the Germanic word. Through a Proto-Indo-European root, it is also linked with Latin flavus ("yellow"; see flavescent and flavine), with Greek phalos (white), French blanc (white, blank) (loaned from Old Frankish), and with Russian белый, belyi ("white," see beluga), and Welsh blawr (grey) all of which derive (according to the American Heritage Dictionary) from the Proto-Indo-European root *bhel- meaning "to shine, flash or burn", (more specifically the word bhle-was, which meant light coloured, blue, blond, or yellow), whence came the names of various bright colours, and that of colour black from a derivation meaning "burnt" (other words derived from the root *bhel- include bleach, bleak, blind, blink, blank, blush, blaze, flame, fulminate, flagrant and phlegm).
blue is a bad colour becasue it is not red which is the colour of elmoIn 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).[3]
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.

Politics
 |
- Blue has been associated with a variety of political positions, often differentiated from communist red or anarchist black. During the revolt in the Vendée against the French revolution, blues stood for the revolutionary forces, and white for the counter-revolutionaries. Later movements like the Breton blues used the colour to signify allegiance to the ideals of the revolution. [citation needed]
- In the United Kingdom and Canada blue is the colour of the respective Conservative Parties. In the United States, however, it has become fashionable since the 2000 Presidential Election to refer to the Democratic Party as "blue" and the Republican Party as "red", particularly as in reference to "red states and blue states".
- The Blue Dog Democrats are a group of conservative Democrats in the United States House of Representatives.[citation needed]
Religion
- Blue in Hinduism: Many of the gods are depicted as having blue-coloured skin, particularly those associated with Vishnu, who is said to be the Preserver of the world and thus intimately connected to water. Krishna and Ram, Vishnu's avatars, are always blue. Shiva, the Destroyer, is also depicted in light blue tones and is called neela kantha, or blue-throated, for having swallowed poison in an attempt to turn the tide of a battle between the gods and demons in the gods' favour.
- Blue in Judaism: In the Torah[6], the Israelites were commanded to put fringes, tzitzit, on the corners of their garments, and to weave within these fringes a "twisted thread of blue (tekhelet)".[7] In ancient days, this blue thread was made from a dye extracted from a Mediterranean snail called the hilazon. Maimonides claimed that this blue was the colour of "the clear noonday sky"; Rashi, the colour of the evening sky.[8] According to several rabbinic sages, blue is the colour of God's Glory.[9] Staring at this colour aids in mediation, bringing us a glimpse of the "pavement of sapphire, like the very sky for purity", which is a likeness of the Throne of God.[10] (The Hebrew word for glory.) Many items in the Mishkan, the portable sanctuary in the wilderness, such as the menorah, many of the vessels, and the Ark of the Covenant, were covered with blue cloth when transported from place to place.[11]
Symbolism
- In Thailand, blue is associated with Friday on the Thai solar calendar. Anyone may wear blue on Fridays and anyone born on a Friday may adopt blue as their colour. The Thai language, however, is one that has had trouble distinguishing blue from green. The default word for Blue was recently สีน้ำเงิน literally, the colour of silver, a poetical reference to the silvery sheen of the deep blue sea. It now means Navy Blue, and the default word is now สีฟ้า literally, the colour of the sky.[12]
- In the early 1960s, the United States Air Force ran a television commercial with this jingle:
They took the blue from the skies
And the pretty girls' eyes
And a touch of Old Glory too;
And gave it to the men who proudly wear the U. S. Air Force Blue!

Variations of blue in culture
- Dark clothing for males such as dark blue business suits have become much more popular since about 1995[citation needed], as opposed to the pastel coloured business suits worn in the 1970s by major leaders in such institutions as the United States Congress (the vast difference in the clothing worn in the 1970s as opposed to the 2000s can be readily seen by looking at a videotape of the Watergate hearings).
- Dark Blue is a 2002 film directed by Ron Shelton.
Law Enforcement
- Police normally wear dark blue or, sometimes, medium blue uniforms (However, the New Age philosopher Alan Watts suggested in the 1960s that police ought to wear baby blue uniforms.).
- Dark Blue is a song on the 2005 CD Everything in Transit, the debut album of Jack's Mannequin.
- In the bandana code of the gay leather subculture, wearing a medium blue bandana means one is into the fetish of having sex with someone who is wearing a police uniform. [14]
- Dark blue represents knowledge, power, integrity, and seriousness. In Western civilization, those in the upper classes in high places of political or economic power often wear dark blue suits. Ordinary members of the working class (especially those who work in the computer industry) often refer derisively to these management functionaries as the suits. [15] This terminology is also used in the television industry--the network executives are often referred to by the creative people (actors, directors, and screenwriters) as the suits. [16]
- In historical atlases published in Germany, light blue is traditionally used as a colour to represent Germany, as opposed to pink for England, purple for France, and light green for Russia. [17]
