Resonant Quell Crimson

#e00140
Notes

Resonant Quell Crimson (#E00140) 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 (343°, 99%, 44%) 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

Resonant
adjective

Latin resonāns, echoing — present-participle of resonate, sharing root with sonance. As a color modifier, resonant implies a saturated-and-deep-vibrating quality where the hue carries low-frequency visual richness. Sits at the bold-and-resonant end of the grid, parallel to sonorous and resounding in usage.

Quell
modifier

Old English cwellan, to-kill-or-suppress. As a color modifier, quell implies a stilled-and-suppressed-and-pacified quality, the visual register of vesper-bell-and-curfew-quell hand-stilled-and-pacified-and-suppressed vesper-bell-and-curfew-bell-and-night-watch quelled-and-stilled-and-suppressed surfaces under vesper-bell-and-curfew-bell-and-night-watch hush-and-stillness-and-quiet bell-tower-and-monastery light. Sits at the modifier-and-mood end of the grid, parallel to hush and lull 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.
