Hefty Yore Crimson

#910e3a
Notes

Hefty Yore Crimson (#910E3A) is a deep 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 (340°, 82%, 31%) places it in the highly saturated band at a dark 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

Hefty
adjective

Old English hefig, heavy — adjectival suffix -y. As a color modifier, hefty implies a saturated-and-substantial-and-weighty quality where the hue carries the visual heft of a hand-cast pig-iron object. Sits at the bold-and-weighty end of the grid, parallel to substantial and weighty in usage.

Yore
modifier

Old English gēara, of-old / long-ago. As a color modifier, yore implies a long-ago-and-storied quality, the visual register of medieval-and-classical-period multi-millennia faded-and-storied long-ago-and-time-deep history-laden surfaces under multi-millennia long-ago-and-time-deep faded light. Sits at the modifier-and-time end of the grid, parallel to eld and past 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.
