Pastoral Goshawk

#17181f
Notes

Pastoral Goshawk (#17181F) is a deep blue 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 (233°, 15%, 11%) 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 amber. 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.

Goshawk
noun

Eurasian Accipiter gentilis — a Accipitridae large forest-raptor of European-and-North-Asian boreal-forest canopies, with deep-glossy-blue-gray dorsal-feathers and a barred-white ventral-feather pattern. Goshawk color refers to a Accipiter gentilis female adult dorsal-feather field in raking light: a dark cool-gray with the matte finish of melanin-pigmented forest-raptor-and-cryptic feather barbs.

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 = 0.014) — 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.
