Lionhearted Chrome

#b33b0c
Notes

Lionhearted Chrome (#B33B0C) is a true orange 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 (17°, 87%, 37%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lionhearted
adjective

Old English lēona-heorte, lion's-heart — referring to Richard I Lionheart (1157–1199). As a color modifier, lionhearted implies a saturated-and-courageous-and-royal quality, the deep-rich color of Crusader-period English Plantagenet-royalty armorial bearings. Sits at the bold-and-chivalrous end of the grid, parallel to valiant and heroic.

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.
