Striking Whitsundays

#19b242
Notes

Striking Whitsundays (#19B242) is a true green with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (136°, 75%, 40%) 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

Striking
adjective

The progressive participle of strike, to hit. Used as a color word since the seventeenth century for hues that command immediate attention. Striking red, striking blue: the implication is saturation combined with visual impact. Sits at the bright-bucket center alongside bold and punchy.

Whitsundays
noun

The Australian archipelago in the central Great Barrier Reef — and the saturated turquoise of Whitehaven Beach's silica-sand-and-tidal-water boundary. Whitsundays refers to Hill Inlet at Whitehaven: a saturated, slightly cool deep blue-green with the optical complexity of tidal water swirling through pure silica sand.

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.
