Gleaming Cornwall

#4fab1b
Notes

Gleaming Cornwall (#4FAB1B) is a true lime 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 (98°, 73%, 39%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Gleaming
adjective

The progressive participle of gleam, to shine intermittently. Used as a color word for hues with the slight optical motion of a polished or wet surface. Gleaming gold, gleaming red: the implication is luminance combined with the optical impression of specular highlight. Sits in the bright-and-glossy corner alongside lustrous.

Cornwall
noun

The southwestern English county — and the rolling green hills of Cornish moors and the Cornish Heritage Coast hedgerows. Cornwall color refers to a Cornish hillside in late spring: a saturated, slightly cool deep yellow-green with the matte finish of grazed pasture grass. Drier than verdant.

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.
