Pastoral Jet

#171d1b
Notes

Pastoral Jet (#171D1B) is a deep teal 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 (160°, 12%, 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pastoral
adjective

Latin pāstōrālis, of-shepherds — adjectival suffix -al. As a color modifier, pastoral implies a neutral-and-shepherding-and-rural quality, the neutral color of Beethoven-Pastoral-Symphony and Constable-Stour-Valley-painting idyllic-rural-shepherding pastoral-mood color treatment. Sits at the neutral-and-traditional end of the grid, parallel to country and rural in usage.

Jet
noun

Fossilized wood from the Araucaria coniferous trees of the Jurassic period — compressed for 180 million years into a hard, polishable lignite. Mined principally at Whitby on the Yorkshire coast since the Bronze Age and worn as Victorian mourning jewelry after Albert's death in 1861. The color refers to a polished Whitby jet cabochon: a deep, slightly muted near-black with the satin finish of fossilized wood.

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 = 0.010) — 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.
