Forthright Via Crimson

#ab1922
Notes

Forthright Via Crimson (#AB1922) is a true red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (356°, 74%, 38%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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.

Etymology

Forthright
adjective

Old English forð-riht, straight ahead, direct. Used as a color modifier in Anglo-Saxon-revival contexts for hues that read as honest and unguarded. Forthright red, forthright blue: the saturation is full, the hue is presented without ornamentation or qualification. Sits in the bold-bucket center alongside frank and direct.

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. Sits at the modifier-and-Latin end of the grid, parallel to arbor and domus in usage.

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.
