Stilled Plume
Stilled Plume (#5E5849) is a deep amber 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 (43°, 13%, 33%) places it in the muted 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
The past participle of still, to make quiet — used as a color modifier in literary contexts for hues that read as deeply at rest. Stilled gray, stilled white: very low saturation combined with optical stillness. Sits at the neutral-bucket alongside tranquil and quiet.
Latin plūma, feather — adopted into English for the cool-pale-gray smokestack and eruption-column aerosol-plume, particularly the Mount-St-Helens-1980 and Pinatubo-1991 eruption-plumes. Plume color refers to a Pinatubo-eruption-1991 eruption-column plume in mid-eruption raking light: a balanced cool gray with the optical complexity of cooling-rate-quenched tephra-and-water-vapor scattering against tropical-volcanic-arc atmospheric humidity.

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.
