Settled Fern
Settled Fern (#357831) is a deep green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (117°, 42%, 33%) 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
The past participle of settle, to come to rest — used as a color modifier since the seventeenth century for hues that read as stabilized after a process. Settled green, settled brown: moderate saturation combined with optical permanence. Sits at the crisp-bucket alongside steady and composed.
The Polypodiopsida — vascular spore-bearing plants that dominated terrestrial flora during the Carboniferous, when their compressed bodies became most of the world's coal. The color refers to the upper surface of a healthy mid-summer fern frond: a saturated, slightly muted green with the matte finish of mature pinnae. Deeper than moss, cooler than chartreuse, with the patient persistence of a plant family three hundred million years old.

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.
