Velvety Sumatra
Velvety Sumatra (#259A34) 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 (128°, 61%, 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
An adjectival form of velvet, used since the eighteenth century for colors that read as if they had the matte light-absorbing quality of velvet. Implies high saturation combined with a non-glossy surface — the matte richness of a deep wine in a fabric rather than in a glass. Sits in the bold-and-deep corner of the grid alongside plush and lush.
The Indonesian island — home to the Sumatran orangutan, tiger, and rhinoceros — and the deep green of Sumatran rainforest and Coffea arabica coffee plantations. Sumatra color refers to a Sumatran highland coffee plantation: a saturated, slightly cool deep green with the matte finish of broad-leaved coffee shrubs.

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.
