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 #b9bbcb

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
  • Brand accents, badges and data highlights
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 #363849
Safe as a 1px border on white
No — use #9093AD

Meaning and mood

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

trustedcalmcompetentcorporate

The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed.

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

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

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.

#b9bbcb, answered

What color is #b9bbcb?

#b9bbcb is a light muted blue, closest to Light Steel Blue (ΔE2000 7.3). It sits at 233° on the hue wheel with 15% saturation and 76% lightness, which reads as cool.

What is the RGB value of #b9bbcb?

rgb(185, 187, 203) — 185 red, 187 green and 203 blue out of 255, or 72.5% / 73.3% / 79.6% by channel.

What is #b9bbcb in HSL and HSV?

hsl(233, 15%, 76%) and hsv(233, 9%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b9bbcb a light or a dark color?

It is a light color. Relative luminance is 0.5017 and perceived brightness is 74%, so black text on it reaches 11.03:1.

Should I use black or white text on #b9bbcb?

Black. It scores 11.03:1 against #b9bbcb, versus 1.90:1 for white — AAA at any size.

Is #b9bbcb accessible on a white background?

#b9bbcb on white scores 1.90:1, which fails WCAG AA at every size. Darken it to #707495 to reach 4.5:1, or #535670 for 7:1.

What is the complementary color of #b9bbcb?

#CBC9B9 sits directly opposite on the wheel. Softer options are the split-complements #CBC0B9 and #C4CBB9, which give the same contrast with far less vibration.

What colors go well with #b9bbcb?

For interface work: #F6F6F8 as the surface, #D0D2DC for borders, #626684 for secondary text, #796A53 as an accent and #363849 for hover and pressed states. For a palette, the analogous pair #B9C4CB and #C0B9CB stays calm, while #CBC9B9 is the loudest partner.

What is #b9bbcb in CMYK for printing?

cmyk(9%, 8%, 0%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b9bbcb warm or cool?

Cool — it scores 66 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #BEB9CB; nudged cooler, #B8C1CC.

Which Tailwind color is closest to #b9bbcb?

The zinc family — its 500 step is #71717a, ΔE2000 24.3 away. That is a visible difference, so define #b9bbcb as a custom token rather than reaching for the built-in.

How do I use #b9bbcb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b9bbcb] or text-[#b9bbcb], 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 #b9bbcb with 50% opacity?

rgba(185, 187, 203, 0.5), or #b9bbcb80 in eight-digit hex. Over white that composites to #DCDDE5; over black, #5D5E66.

Is #b9bbcb a web-safe color?

No. The nearest web-safe colour is #CCCCCC, ΔE2000 8.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #b9bbcb mean?

As a blue, it reads trusted, calm, competent. The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed. At this low chroma the association is faint; it behaves more like a neutral.

What gradient works with #b9bbcb?

The safest is same-hue elevation: linear-gradient(135deg, #DCDDE5, #b9bbcb 45%, #363849). For more colour, a short hue run to #B6A7BE keeps it rich without turning muddy.
