Using this color

Where #b4b1be works

#B4B1BE (#b4b1be) sits in the indigo family at about 254° hue, 9% saturation, and 72% lightness. Contrast is 2.11:1 on white and 9.97:1 on black, so near-black labels read more clearly on the swatch itself. Nearest Tailwind token: zinc-400 (approximation unless the hex is an official scale stop).

Sensible jobs for this swatch

subtle surfaces, chips, and table stripes
text or icons on charcoal / dark mode

Do not use #b4b1be as small body text on white — 2.11:1 misses WCAG AA (4.5:1). Pair it with a darker shade from the scale below, or check pairs in the contrast checker.

Low saturation makes this easy to overuse as a neutral. Keep one chromatic accent elsewhere so the interface does not go muddy.

Family context: Intuition, depth, and sincerity. Common in enterprise software and thoughtful products. Common uses still include buttons, charts, and accents in the Indigo range — always verify the pair for this exact hex in the contrast checker.
