Buzzed Tropics

#3fd478
Notes

Buzzed Tropics (#3FD478) is a true green 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 (143°, 63%, 54%) 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

Buzzed
adjective

Imitative-onomatopoeic origin — past-participle of buzz, evoking the sound of bee-hum. As a color modifier, buzzed implies a saturated-and-vibrating-and-active quality, the bright color of insect-pollinator and neon-lamp low-amplitude-buzz visual-vibration. Sits at the bright-and-active end of the grid, parallel to jazzed and wired in usage.

Tropics
noun

The Earth's equatorial belt between the Tropic of Cancer and the Tropic of Capricorn — the region of the world where the sun reaches direct overhead at some point of the year. Tropics refers to the unifying blue-green of tropical-zone ocean and lagoon water: a saturated, slightly cool deep blue-green.

Wide gamut

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.
