Majestic Matcha

#428f1f
Notes

Majestic Matcha (#428F1F) 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 (101°, 64%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Majestic
adjective

Latin māiestātis, majesty — adjectival suffix -ic. As a color modifier, majestic implies a saturated-and-imposing-grandeur quality, the deep-rich color of Salisbury-Cathedral-and-Chartres-Cathedral Gothic-architecture monumental presence against the open sky. Sits at the bold-and-imposing end of the grid, parallel to regal and imperial.

Matcha
noun

The shade-grown, stone-ground green tea of the Japanese tea ceremony — leaves of Camellia sinensis covered for weeks before harvest to concentrate chlorophyll, then powdered in a granite mill. The color refers to ceremonial-grade matcha whisked in hot water: a saturated, slightly muted green with the powdery finish of micron-scale leaf particles. Brighter than sage, deeper than lime, with the meditative weight of a 600-year-old practice.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
