Decisive Gloss Crimson

#b72423
Notes

Decisive Gloss Crimson (#B72423) 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 (0°, 68%, 43%) 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

Decisive
adjective

From the Latin decidere, to cut off — used as a modifier for colors that read as firm and final. Decisive black, decisive red: the implication is that the color has settled on its position and won't drift. Sits in the bold-bucket corner alongside resolute, with a slightly sharper edge.

Gloss
modifier

Old Norse glosi, glossy-shine. As a color modifier, gloss implies a polished-and-reflective-shine quality, the visual register of polished-and-glossy-leather-and-lacquer hand-polished-and-glossy lacquer-and-shellac-and-varnish polished-and-glossy-shine surfaces under polished-and-glossy-lacquer workshop-light. Sits at the modifier-and-texture end of the grid, parallel to sheen and shine 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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
