Replete Mossed Crimson

#a91833
Notes

Replete Mossed Crimson (#A91833) 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 (349°, 75%, 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Replete
adjective

Latin replētus, filled — past-participle of replēre. As a color modifier, replete implies a saturated-and-fully-pigmented quality where the hue is completely loaded with its source pigment. Sits at the bold-and-saturated end of the grid, parallel to brimming and suffused in usage.

Mossed
modifier

Old English mos, moss. As a color modifier, mossed implies a moss-covered-and-aged quality, the visual register of English-and-Welsh-mossed-and-lichen-covered moss-and-lichen-covered stone-and-tree-and-cobble mossed-and-lichen-covered surfaces under English-and-Welsh moss-and-lichen-covered atmospheric light. Sits at the modifier-and-texture end of the grid, parallel to pitted and limed 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.
