Heroic Chrome

#a63519
Notes

Heroic Chrome (#A63519) 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 (12°, 74%, 37%) 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

Heroic
adjective

Latin hēroicus, of a hero — derived from Greek hērōs. As a color modifier, heroic implies a saturated-and-monumental-and-victorious quality, the deep-rich color of Wagner-and-Sibelius late-Romantic-era musical-and-painterly heroic-mode. Sits at the bold-and-celebratory end of the grid, parallel to triumphant and valiant.

Chrome
noun

Lead chromate (PbCrO₄) — the chrome orange pigment introduced in 1809, brilliant but heavily toxic and reactive. Largely replaced by cadmium pigments in the twentieth century. The color refers to a freshly mixed chrome-orange in a Victorian color-merchant's stock: a saturated, slightly red orange with the matte finish of lead-based pigment. Brighter than ochre.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
