Sociable Killdeer
Sociable Killdeer (#BAB5BE) is a pale neutral with a mono character. It's a grayscale value, at home in typography, dividers, and the structural layer beneath stronger colors. Its HSL profile (273°, 6%, 73%) places it in the muted band at a light lightness. It works as a soft page background, card surface, or low-key divider. Avoid it for body text against white. Pair it with almost any saturated accent. It's built to sit underneath or behind stronger colors without fighting them.
Etymology
Latin sociābilis, companionable — adjectival suffix -able. As a color modifier, sociable implies a neutral-and-friendly-and-welcoming quality where the hue carries the visual register of Edwardian-and-American-Country friendly-and-welcoming-hosting interior-decoration-and-textile coordinated-color tone. Sits at the neutral-and-friendly end of the grid, parallel to affable and amiable in usage.
North American Charadrius vociferus — a Charadriidae shorebird of cosmopolitan-North-American open-pasture-and-shoreline habitats, with the iconic kill-deer call. Killdeer color refers to a Charadrius vociferus dorsal-feather field in raking summer light: a pale cool gray with the matte finish of melanin-and-buff structurally colored feather barbs against the killdeer's black-bar breast-pattern.
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.

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
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.
