Coruscating Thor Avocado

#81a511
Notes

Coruscating Thor Avocado (#81A511) is a true lime 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 (75°, 81%, 36%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Coruscating
adjective

Latin coruscāns, flashing — present-participle of coruscāre. As a color modifier, coruscating implies a saturated-and-rapidly-flashing quality, the bright color of lightning-strike atmospheric-electrical-discharge against the night-sky. Sits at the bright-and-flashing end of the grid, parallel to flashing and flickering in usage.

Thor
modifier

Old Norse Þórr, god-of-thunder-and-Mjölnir. As a color modifier, thor implies a hammer-Mjölnir-and-thunderbolt-and-red-bearded quality, the visual register of Norse-Thor-and-Mjölnir-hammer hand-hammer-Mjölnir-and-thunderbolt-and-red-bearded Norse-Thor-and-Mjölnir-hammer-and-Asgard thor-and-hammer-Mjölnir-and-thunderbolt surfaces under Norse-Thor-and-Mjölnir-hammer-and-Asgard Bilskirnir-and-Thrudheim-and-thunder-cart thunder-storm-light.

Avocado
noun

Persea americana, the buttery drupe domesticated in Mesoamerica seven thousand years ago and named for the Aztec āhuacatl.

Earthier than pistachio, lighter than olive, with the recent kitchen association of a fruit only recently turned global staple.
