Ironclad Scorpio Crimson

#e02138
Notes

Ironclad Scorpio Crimson (#E02138) 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 (353°, 75%, 50%) 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

Ironclad
adjective

English compound iron + clad — referring to the 19th-century USS-Monitor and CSS-Virginia iron-armored warships. As a color modifier, ironclad implies a saturated-and-armored-and-impenetrable quality where the hue carries the visual weight of forged-iron armor-plate. Sits at the bold-and-fortified end of the grid, parallel to fortified and armored.

Scorpio
modifier

Latin scorpio, scorpion-of-the-zodiac. As a color modifier, scorpio implies a scorpion-and-water-sign-and-Mars-Pluto-ruled-fixed-water quality, the visual register of Hellenic-Scorpio-and-Orion-myth-scorpion hand-scorpion-and-water-sign-and-Mars-Pluto-ruled-fixed-water Hellenic-Scorpio-and-Orion-myth-scorpion-and-Antares scorpio-and-scorpion-and-water-sign surfaces under Hellenic-Scorpio-and-Orion-myth-scorpion-and-Antares mid-autumn-and-October-and-November fixed-water-sign-light. Sits at the modifier-and-zodiac end of the grid, parallel to libra and sagittarius 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.
