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 #b3bbc1

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 #394146
Safe as a 1px border on white
No — use #89959E

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.

#b3bbc1, answered

What color is #b3bbc1?

#b3bbc1 is a light muted blue, closest to Silver (ΔE2000 4.5). It sits at 206° on the hue wheel with 10% saturation and 73% lightness, which reads as cool.

What is the RGB value of #b3bbc1?

rgb(179, 187, 193) — 179 red, 187 green and 193 blue out of 255, or 70.2% / 73.3% / 75.7% by channel.

What is #b3bbc1 in HSL and HSV?

hsl(206, 10%, 73%) and hsv(206, 7%, 76%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b3bbc1 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4897 and perceived brightness is 73%, so black text on it reaches 10.79:1.

Should I use black or white text on #b3bbc1?

Black. It scores 10.79:1 against #b3bbc1, versus 1.95:1 for white — AAA at any size.

Is #b3bbc1 accessible on a white background?

#b3bbc1 on white scores 1.95:1, which fails WCAG AA at every size. Darken it to #697781 to reach 4.5:1, or #505A62 for 7:1.

What is the complementary color of #b3bbc1?

#C1B9B3 sits directly opposite on the wheel. Softer options are the split-complements #C1B3B4 and #C1C0B3, which give the same contrast with far less vibration.

What colors go well with #b3bbc1?

For interface work: #F7F7F8 as the surface, #D2D7DA for borders, #67747E for secondary text, #755D57 as an accent and #394146 for hover and pressed states. For a palette, the analogous pair #B3C1C0 and #B3B4C1 stays calm, while #C1B9B3 is the loudest partner.

What is #b3bbc1 in CMYK for printing?

cmyk(7%, 3%, 0%, 24%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b3bbc1 warm or cool?

Cool — it scores 64 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B3B6C1; nudged cooler, #A3ADB7.

Which Tailwind color is closest to #b3bbc1?

The cyan family — its 500 step is #06b6d4, ΔE2000 20 away. That is a visible difference, so define #b3bbc1 as a custom token rather than reaching for the built-in.

How do I use #b3bbc1 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b3bbc1] or text-[#b3bbc1], 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 #b3bbc1 with 50% opacity?

rgba(179, 187, 193, 0.5), or #b3bbc180 in eight-digit hex. Over white that composites to #D9DDE0; over black, #5A5E61.

Is #b3bbc1 a web-safe color?

No. The nearest web-safe colour is #CCCCCC, ΔE2000 6.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #b3bbc1 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 #b3bbc1?
