the color so rare in nature that creatures fake it with physics, not pigment
means The color of a clear daytime sky or deep water, sitting between green and violet on the spectrum.
from From Old English 'blaw' or 'blæw,' which traveled through Old French 'bleu' before settling into its modern shape — all reaching back to a Proto-Germanic root 'blewaz,' a likely cousin of Latin 'flavus' (yellow), since old color words wandered across the spectrum in ways that puzzle modern eyes. Curiously, many ancient texts barely named blue at all; some scholars note Homer's wine-dark sea and absent skies, hinting that the word arrived late to the human palette.
