Lionhearted Galapagos

#199e3b
Notes

Lionhearted Galapagos (#199E3B) is a true green 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 (135°, 73%, 36%) 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 magenta. 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.

Galapagos
noun

The Ecuadorian volcanic archipelago — Darwin's evolutionary laboratory — and the saturated blue-green of Galapagos lagoon water at Bartolomé Island. Galapagos refers to the cove at Bartolomé: a saturated, slightly cool deep blue-green with the optical clarity of cold Pacific upwelling waters.

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.
