Regal Rosemary

#189b0a
Notes

Regal Rosemary (#189B0A) is a deep green 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 (114°, 88%, 32%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Regal
adjective

Latin rēgālis, kingly — derived from rēx (king). As a color modifier, regal implies a saturated-and-royal-formality quality, the deep-rich color of British-Coronation-period royal vestment-and-mantle and Imperial-State-Crown regalia. Sits at the bold-and-imperial end of the grid, parallel to sovereign and royal in usage.

Rosemary
noun

Salvia rosmarinus, the woody-stemmed Mediterranean shrub whose Latin name means dew of the sea for its preference for coastal habitat. The color refers to mature rosemary needles in summer: a deep, slightly muted green with the resinous finish of a leaf full of camphor and eucalyptol. Drabber than basil, warmer than thyme, with the kitchen-and-garden weight of a herb used for poultry, lamb, and remembrance.

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.
