the color your brain sees first, last, and in your dreams of danger.
means The color at the long-wavelength end of the visible spectrum, seen in blood, fire, ripe fruit, and warning signs.
from From Old English 'rēad,' rooted in the Proto-Germanic '*raudaz' and traceable back to the Proto-Indo-European '*h₁rewdʰ-,' a color-word so ancient it seeded a whole family — Latin 'ruber' (red), 'rufus' (reddish), the 'rubies' and 'rubric' that follow, and likely cousins like 'rust' and 'ruddy.' One of humanity's oldest named colors, fittingly born from the words for blood and ore.
