### Etymology 1

From Middle English blewe, from Anglo-Norman blew (“blue”), from Middle French bleu, from Old French blöe, bleve, blef (“blue”), from Frankish *blāu (“blue”) (perhaps through a Late Latin blāvus, blāvius (“blue”) attested from Isidore of Seville), from Proto-Germanic *blēwaz (“blue, dark blue”), from Proto-Indo-European *bʰlēw- (“yellow, blond, grey”). Cognate with dialectal English blow (“blue”), Scots blue, blew (“blue”), North Frisian bla, blö (“blue”), Saterland Frisian blau (“blue”), Dutch blauw (“blue”), German blau (“blue”), Danish, Norwegian and Swedish blå (“blue”), Icelandic blár (“blue”), Latin flāvus (“yellow”), Middle Irish blá (“yellow”). Doublet of blow.
Possibly related also to English blee (“colour”), from Old English blēo (“colour”); but direct derivatives of Proto-Germanic *blēwaz (“blue, dark blue”) in Old English include: Old English blāw and blēo (“blue”), Old English blǣwen (“bluish, light-blue”), blǣhǣwen (“blue-coloured, bluish, violet or purple colour”, literally “blue-hued”). There seems to be a parallel connection in Germanic between words for blue and colour, dually exemplified by Proto-West Germanic *blīu (“colour, blee”) and *blāu (“blue”); and Proto-Germanic *hiwją (“colour, hue”) and *hēwijaz (“blue, purple”).
The sense "obscene, pornographic" is apparently from the colour; various theories exist as to how it arose, including that it is from the colour of the envelopes used to contain missives of the censors and managers to vaudevillian performers on objectionable material from their acts that needed to be excised. (Can this etymology be sourced?)
