Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

How to use #b0acb2

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Borders, dividers and quiet backgrounds
  • Long-form reading surfaces
  • Card and section backgrounds
  • Neutral UI chrome and typography
Use with care
  • Text of any size on white — fails WCAG AA
  • White text placed on it
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #413D42
Safe as a 1px border on white
No — use #979299

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

neutralquieteditorialengineered

Grey is the material the rest of the interface is built from: type, rules, surfaces, disabled states.

With almost no chroma left, the family association is barely present; treat it as a neutral that happens to lean this way. The lightness keeps it airy and approachable.

Worth knowing

Mid-greys are where accessibility quietly fails — check every step of your ladder, not just the ends.

Bottom row of hexes is the flattened result over white — use those when a design tool refuses transparency, or when you need a solid fallback.

#b0acb2, answered

What color is #b0acb2?

#b0acb2 is a light muted gray, closest to Dark Gray (ΔE2000 4.4). It sits at 280° on the hue wheel with 4% saturation and 69% lightness, which reads as neutral.

What is the RGB value of #b0acb2?

rgb(176, 172, 178) — 176 red, 172 green and 178 blue out of 255, or 69% / 67.5% / 69.8% by channel.

What is #b0acb2 in HSL and HSV?

hsl(280, 4%, 69%) and hsv(280, 3%, 70%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b0acb2 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4195 and perceived brightness is 68%, so black text on it reaches 9.39:1.

Should I use black or white text on #b0acb2?

Black. It scores 9.39:1 against #b0acb2, versus 2.24:1 for white — AAA at any size.

Is #b0acb2 accessible on a white background?

#b0acb2 on white scores 2.24:1, which fails WCAG AA at every size. Darken it to #78727B to reach 4.5:1, or #5C575E for 7:1.

What is the complementary color of #b0acb2?

#AEB2AC sits directly opposite on the wheel. Softer options are the split-complements #B1B2AC and #ACB2AD, which give the same contrast with far less vibration.

What colors go well with #b0acb2?

For interface work: #F7F7F8 as the surface, #D7D5D8 for borders, #746F77 for secondary text, #676E5E as an accent and #413D42 for hover and pressed states. For a palette, the analogous pair #ADACB2 and #B2ACB1 stays calm, while #AEB2AC is the loudest partner.

What is #b0acb2 in CMYK for printing?

cmyk(1%, 3%, 0%, 30%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b0acb2 warm or cool?

Neutral — it scores 51 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #BFB3AA; nudged cooler, #9EA9B6.

Which Tailwind color is closest to #b0acb2?

The neutral family — its 500 step is #737373, ΔE2000 20.2 away. That is a visible difference, so define #b0acb2 as a custom token rather than reaching for the built-in.

How do I use #b0acb2 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b0acb2] or text-[#b0acb2], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.

What is #b0acb2 with 50% opacity?

rgba(176, 172, 178, 0.5), or #b0acb280 in eight-digit hex. Over white that composites to #D8D6D9; over black, #585659.

Is #b0acb2 a web-safe color?

No. The nearest web-safe colour is #999999, ΔE2000 7.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #b0acb2 mean?

As a gray, it reads neutral, quiet, editorial. Grey is the material the rest of the interface is built from: type, rules, surfaces, disabled states. At this low chroma the association is faint; it behaves more like a neutral.

What gradient works with #b0acb2?

The safest is same-hue elevation: linear-gradient(135deg, #CECCCF, #b0acb2 45%, #413D42). For more colour, a short hue run to #A39CA0 keeps it rich without turning muddy.
