The story of Blu
Blue arrived in English in the thirteenth century and pushed aside the native words, and it has since collected more figurative senses than any other color term in the language — sadness, loyalty, nobility, obscenity, music. As a given name it is very recent and thoroughly American, used for sons and daughters alike, and it belongs to the small group of color names — Blue, Indigo, Scarlett, Sage — that have crossed from vocabulary into naming. The Blu spelling is the more common of the two as a name.
Meaning
the color blue
English blue comes from Old French bleu, which came into French from a Germanic word — so the word made a loop through France to get here, and displaced the Old English word it was related to. The reading is exact. The dropped e is a modern American respelling and changes nothing.

The Walid test
Every popular name lives one long story — a climb, a peak, a slow settling back. Blu's later chapters haven't been written yet, so we borrowed them: Walid climbed just as high around 1998, and its whole arc is on record. Line the two peaks up, and Walid's path sketches the road Blu is walking now.

- Blue and Blu are both in use and the e gets added by strangers.
- Color names are strongly tied to the decade that made them fashionable.
