Majestic Vesper Forest
Majestic Vesper Forest (#1AA139) is a true 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 (134°, 72%, 37%) 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
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.
Latin vespera, evening. As a color modifier, vesper implies an evening-prayer-and-dusk quality, the visual register of Roman-Catholic-and-Orthodox-Vespers evening-prayer-and-dusk hour-of-day evening-prayer-and-incense liturgical surfaces under Vespers-and-Compline ecclesiastical-evening candlelight. Sits at the modifier-and-time end of the grid, parallel to eve and knell in usage.
The dense canopy of a temperate or tropical woodland — oak, beech, pine, eucalyptus, mahogany — wherever leaves close above to filter the light below. Forest green refers to the average reflectance of a healthy mid-summer canopy seen from below: a saturated, slightly muted green with the matte finish of layered chlorophyll. Deeper than fern, cooler than olive, with the ecological weight of a word that has named every wooded biome on Earth.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
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.
