Lionhearted Coronet

#634eb2
Notes

Lionhearted Coronet (#634EB2) is a true indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (253°, 39%, 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 yellow. 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.

Coronet
noun

Old French coronete, little crown — a small ornamental crown worn by lower-rank European nobility (dukes, earls, viscounts, barons) and Crown Princes of Britain. The coronet of an English duke is set with deep-blue sapphire. Coronet color refers to an English duke's coronet with its sapphire alternation: a saturated, slightly cool deep blue-violet with the glassy finish of polished Ceylon sapphire on gilt metal.

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.
