Quickening Borneo

#40ae3d
Notes

Quickening Borneo (#40AE3D) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (118°, 48%, 46%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Quickening
adjective

Old English cwic, living / lively — present-participle of quicken. As a color modifier, quickening implies a saturated-and-coming-alive-and-active quality where the hue accelerates visual engagement. Sits at the bright-and-active end of the grid, parallel to animated and invigorating in usage.

Borneo
noun

The Southeast Asian island — and the saturated deep green of Borneo rainforest, home to one of the world's three remaining great-ape populations (Pongo pygmaeus, the Bornean orangutan). Borneo color refers to a Sarawak jungle canopy: a saturated, slightly cool deep green with the matte finish of dense tropical foliage.
