Warm Stratocumulus

#9fa6a4
Notes

Warm Stratocumulus (#9FA6A4) is a balanced 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 (163°, 4%, 64%) places it in the muted band at a mid lightness. It works well as secondary text, borders, and placeholder states. A reliable middle gray that reads cleanly in either light or dark contexts. Pair it with almost any saturated accent. It's built to sit underneath or behind stronger colors without fighting them.

Etymology

Warm
adjective

Old English wearm, of moderate heat — used as a color modifier since the medieval period for hues that read as containing red, orange, or yellow undertones. Warm gray, warm white: not necessarily a temperature, but the optical impression of a slight red-orange shift. Sits across the crisp and neutral buckets.

Stratocumulus
noun

Latin stratus (layer) and cumulus (heap) — the iconic pale-cool-pale-gray low-altitude stratocumulus cloud-form, the most common cloud over the world's oceans. Stratocumulus color refers to a stratocumulus cloud-deck over the Bay-of-Biscay in November-overcast: a pale cool gray with the optical complexity of low-altitude water-droplet scattering against November overcast Atlantic-coast sky.

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 = 0.008) — 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.

WCAG contrast

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.

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.

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.
