Electrifying Lent Eucalyptus

#51d4a2
Notes

Electrifying Lent Eucalyptus (#51D4A2) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (157°, 60%, 57%) 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

Electrifying
adjective

Greek ēléktron, amber — present-participle of electrify, named after the static-electricity property of rubbed amber. As a color modifier, electrifying implies a saturated-and-shocking-and-active quality, the bright color of Tesla-coil high-voltage atmospheric-discharge emission. Sits at the bright-and-active end of the grid, parallel to charged and neon in usage.

Lent
modifier

Latin Lententide, Lent / spring. As a color modifier, lent implies a Lenten-and-fasting-and-purple quality, the visual register of Roman-Catholic-and-Anglican Lenten-period purple-vestment-and-fast-and-ash-Wednesday liturgical surfaces under Lenten-purple ecclesiastical-vestment candlelight. Sits at the modifier-and-time end of the grid, parallel to advent and easter in usage.

Eucalyptus
noun

The genus Eucalyptus, the gum trees that dominate the Australian forest canopy and have been planted across the world for fast-growth timber and the menthol-camphor oil. The color refers to mature eucalyptus leaves with their pale waxy bloom: a soft, slightly muted blue-green with the matte finish of cuticle that reflects more light than typical foliage. Cooler than sage, warmer than mint.

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.
