Established Oregano

#51a71d
Notes

Established Oregano (#51A71D) is a true lime with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (97°, 70%, 38%) 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

Established
adjective

Latin stabilīre, to make stable — past-participle of establish. As a color modifier, established implies a saturated-and-rooted quality where the hue carries the weight of long-standing visual presence. Sits at the bold-and-firm end of the grid, parallel to steadfast and anchored 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.
