Weighty Glint Crimson

#b20821
Notes

Weighty Glint Crimson (#B20821) 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 (351°, 91%, 36%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Weighty
adjective

Old English wegan, to weigh — adjectival suffix -y. As a color modifier, weighty implies a saturated-and-heavy-and-imposing quality where the hue carries visual mass and gravitational presence. Sits at the bold-and-weighty end of the grid, parallel to substantial and hefty in usage.

Glint
modifier

Middle English glent, to-shine-or-glance. As a color modifier, glint implies a brief-and-glancing-and-pinpoint-shine quality, the visual register of Scottish-burn-and-anvil-spark-glint hand-brief-and-glancing-and-pinpoint-shine Scottish-burn-and-anvil-spark-and-flint-strike glinted-and-brief-and-glancing surfaces under Scottish-burn-and-anvil-spark-and-flint-strike sun-on-water-and-forge-spark fleeting-glance-light. Sits at the modifier-and-mood end of the grid, parallel to gleam and spark 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.
