Electrifying Amazon

#39aa36
Notes

Electrifying Amazon (#39AA36) 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°, 52%, 44%) 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

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.

Amazon
noun

The largest river basin and rainforest on Earth — and the unifying deep green of Amazonian canopy seen from above. Amazon color refers to the average reflectance of an unbroken Amazon canopy: a saturated, slightly cool deep yellow-green with the matte finish of high-rainfall tropical foliage.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
