Heartening Woad

#2ac0ca
Notes

Heartening Woad (#2AC0CA) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (184°, 66%, 48%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Heartening
adjective

Old English heorte (heart) — present-participle of hearten. As a color modifier, heartening implies a clear-and-uplifting-and-encouraging quality where the hue carries the visual register of cheerful-encouraging color-tone. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and cheerful in usage.

Woad
noun

Isatis tinctoria, the European blue-dye plant whose leaves yield indigo-equivalent indigotin. Used by Pictish warriors as body paint and the dominant pre-industrial European blue dye until East Indian indigo displaced it in the seventeenth century. The color refers to a freshly woad-dyed wool: a saturated, slightly cool deep blue with the matte finish of plant-and-mordant dye.

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.
