Dominant Spar Forest
Dominant Spar Forest (#378D28) 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 (111°, 56%, 35%) 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
Latin dominārī, to rule — present-participle of dominate. As a color modifier, dominant implies a saturated-and-leading quality where the hue claims visual precedence over neighboring colors in the surrounding palette. Sits at the bold-and-imperative end of the grid, parallel to commanding and authoritative.
Old Norse sparri, long-pole. As a color modifier, spar implies a long-wooden-pole-for-sail quality, the visual register of Tall-Ship-and-Royal-Navy-spar hand-cut long-wooden-pole-and-spar-for-sail mast-and-yard-and-boom maritime-rigging surfaces under tall-ship-spar-and-yard maritime-rigging light. Sits at the modifier-and-nautical end of the grid, parallel to mast and boom 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.
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.
