Shaker Whetstone

#1f1b15
Notes

Shaker Whetstone (#1F1B15) 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 (36°, 19%, 10%) 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

Shaker
adjective

English Shaker, United-Society-of-Believers-in-Christ's-Second-Appearing — adjectival usage of Shaker. As a color modifier, shaker implies a neutral-and-plain-and-stripped-down quality, the neutral color of Shaker-furniture-and-craft anti-ornamental-and-functional hand-built-and-precise-craft surface-finish. Sits at the neutral-and-stripped-down end of the grid, parallel to quakerly and plain in usage.

Whetstone
noun

Old English hweott-stān, sharpening-stone — the medieval European Charnley Forest and Welsh slate-grit honing-stones used to sharpen knives-and-axes. Whetstone color refers to a Charnley-Forest honing-stone face in raking light: a dark cool-gray with the matte finish of Carboniferous-period slate-grit-and-quartz fine-grained metamorphic rock on a hand-quarried hand-cut English honing-stone.

Closest matches

The nearest named color in three reference sources, ranked by perceptual distance (ΔE76 in CIELAB). ΔE < 1 is imperceptible to most viewers; ΔE > 10 is clearly different. When two sources point to the same hex they’re merged into one tile; click any to open that color’s page.

Harmonies

This color has effectively no chroma (OKLCH C = 0.013) — it’s on the grayscale axis. Hue rotations don’t change a grayscale color, so complementary, analogous, triadic, and split-complementary all reduce to the same value. They aren’t shown because four identical tiles would be misleading.

Accessibility

Color-vision simulation

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.

Display P3 representation

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.
