Cottony Hessian
Cottony Hessian (#909C7F) is a true lime 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 (85°, 13%, 55%) places it in the muted 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Arabic qutn, cotton — adjectival suffix -y. As a color modifier, cottony implies a pale-and-fluffy-and-soft quality, the pale color of Mississippi-Delta-and-Egyptian-Nile-Delta freshly-picked-and-ginned cotton-fiber-and-boll soft-and-fluffy textile-finish. Sits at the pale-and-soft end of the grid, parallel to fluffy and fleecy in usage.
A coarse jute fabric — used for sacking, packaging, and rough textile applications. Originally manufactured in Hesse (Germany), where the Hessian troops of the American Revolution wore yellow uniforms. Hessian refers to undyed natural hessian fabric: a soft, slightly muted warm tan with the textured matte finish of bast-fiber weave. Slightly warmer than burlap.

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 sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
