Steely Shiroshōzoku
Steely Shiroshōzoku (#B0BBB3) 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 (136°, 7%, 71%) 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
An adjectival form of steel — used as a color modifier since the eighteenth century for hues with the slight blue-gray of tempered or polished steel. Steely gray, steely blue: moderate-to-low saturation combined with the optical impression of metallic surface. Sits in the neutral-and-cool corner alongside cold.
Japanese 白装束, white formal-attire — the iconic pale-cream-white silk ceremonial-and-funerary kimono of Heian-and-Kamakura-period Imperial-Court tradition. Shiroshōzoku color refers to a Heian-period Imperial-Court shiroshōzoku funerary-silk: a pale cool gray with the silk luster of pure-white tussah silk hand-woven for ceremonial use. Distinct from the cooler shiromuku bridal-white.

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.
