Lionhearted Nineveh

#a55ae4
Notes

Lionhearted Nineveh (#A55AE4) is a true indigo with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (273°, 72%, 62%) 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 lime. 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.

Nineveh
noun

Assyrian capital (modern Mosul, Iraq) — the imperial court of Sennacherib (705–681 BCE), where Tyrian purple tribute textiles were imported from the Phoenician coast. Nineveh color refers to an Assyrian-court purpura-bordered tribute textile in the Library of Ashurbanipal: a saturated, slightly cool deep violet with the matte finish of multi-bath shellfish dye on hand-loomed Mesopotamian wool.
