Lionhearted Copper
Lionhearted Copper (#BE6322) is a true orange with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (25°, 70%, 44%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
Element Cu, atomic number 29 — one of the first metals worked by humans, smelted in Anatolia and the Levant by the fourth millennium BCE. The color refers to freshly polished copper before oxidation: a warm, slightly red metallic orange with the satin finish of a coin or a kettle. Left in air, it dulls to brown; left in salt air, it greens to verdigris. The starting color of every copper roof.
