Lurid Oregano

#51ab25
Notes

Lurid Oregano (#51AB25) 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 (100°, 64%, 41%) 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

Lurid
adjective

Latin lūridus, pale-yellow / sickly — sharing root with lūror (yellowish-pallor). As a color modifier, lurid implies a saturated-and-shocking-and-sickly-bright quality, the bright color of Penny-Dreadful-and-Pulp-Fiction sensational-cover-art bright-and-pulpy printing. Sits at the bright-and-shocking end of the grid, parallel to garish and gaudy in usage.

Oregano
noun

Origanum vulgare, the Mediterranean herb essential to Italian and Greek cooking — pizza, salsa pomodoro, Greek salad dressings. The color refers to fresh oregano sprigs in a Greek kitchen: a saturated, slightly muted yellow-green with the matte finish of small clustered mint-family leaves.

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.
