Buttressed Via Crimson

#db3713
Notes

Buttressed Via Crimson (#DB3713) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (11°, 84%, 47%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Via
modifier

Latin via, road-or-way. As a color modifier, via implies a Latin-road-and-Roman-Via-Appia quality, the visual register of Roman-Via-Appia-and-Via-Aemilia hand-Latin-road-and-Roman-Via-Appia Roman-Via-Appia-and-Via-Aemilia-and-Via-Egnatia via-and-Latin-road surfaces under Roman-Via-Appia-and-Via-Aemilia-and-Via-Egnatia Republican-Rome-and-imperial-road-network basalt-paved-Roman-road-light.

Crimson
noun

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.
