Lionhearted Berry

#243ea7
Notes

Lionhearted Berry (#243EA7) is a true blue with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (228°, 65%, 40%) 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 amber. 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.

Berry
noun

A general-purpose color name for the deep blue-purple of Vaccinium blueberries, Sambucus elderberries, and the Aronia black-chokeberries that mark hedgerows in autumn. The color refers to a ripe wild blueberry's bloom-coated skin: a deep, slightly violet-shifted blue with the powdery finish of waxy fruit. Cooler than wine, warmer than indigo, with the foraged-fruit specificity of a word that covers half-a-dozen species.

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.
