Word Origin & History

blue 
c.1300, bleu, blwe, etc., from O.Fr. bleu, from Frank. blao, from P.Gmc. *blæwaz, from PIE base *bhle-was "light-colored, blue, blond, yellow." "The exact color to which the Gmc. term applies varies in the older dialects; M.H.G. bla is also "yellow," whereas the Scandinavian words may refer esp. to a deep, swarthy black, e.g. O.N. blamaðr, N.Icel. blamaður 'Negro' " [Buck]. Replaced O.E. blaw, from the same PIE root, which also yielded L. flavus "yellow," O.Sp. blavo "yellowish-gray," Gk. phalos "white," Welsh blawr "gray," O.N. bla "livid" (the meaning in black and blue), showing the usual slippery definition of color words in I.E. The present spelling is since 16c., from Fr. influence. The color of constancy since Chaucer at least, but apparently for no deeper reason than the rhyme in true blue (1500). Blue (adj.) "lewd" is recorded from 1840; the sense connection is unclear, and is opposite to that in blue laws (q.v.). Blueprint is from 1886; the fig. sense of "detailed plan" is first attested 1926. For blue ribbon, see cordon bleu under cordon. Blue moon emblematic of "very rarely" suggests something that, in fact, never happens (cf. at the Greek calends), as in this couplet from 1528:
Yf they say the mone is blewe,
We must beleve that it is true.
Many IE languages seem to have had a word to describe the color of the sea, encompasing blue and green and gray; e.g. Ir. glass (see Chloe), O.E. hæwen "blue, gray," related to har (see hoar), Serbo-Cr. sinji "gray-blue, sea-green," Lith. šyvas, Rus. sivyj "gray."

Blue

generally associated with purple (Ex. 25:4; 26:1, 31, 36, etc.). It is supposed to have been obtained from a shellfish of the Mediterranean, the Helix ianthina of Linnaeus. The robe of the high priest's ephod was to be all of this colour (Ex. 28:31), also the loops of the curtains (26:4) and the ribbon of the breastplate (28:28). Blue cloths were also made for various sacred purposes (Num. 4:6, 7, 9, 11, 12). (See COLOUR.)
