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 #b9bfd1

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary 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 #33394D
Safe as a 1px border on white
No — use #8892B1

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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.

Transparency

What each alpha value actually composites to. The top row is #b9bfd1 over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

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.

#b9bfd1, answered

What color is #b9bfd1?

#b9bfd1 is a light soft blue, closest to Light Steel Blue (ΔE2000 5.3). It sits at 225° on the hue wheel with 21% saturation and 77% lightness, which reads as cool.

What is the RGB value of #b9bfd1?

rgb(185, 191, 209) — 185 red, 191 green and 209 blue out of 255, or 72.5% / 74.9% / 82% by channel.

What is #b9bfd1 in HSL and HSV?

hsl(225, 21%, 77%) and hsv(225, 11%, 82%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b9bfd1 a light or a dark color?

It is a light color. Relative luminance is 0.5218 and perceived brightness is 75%, so black text on it reaches 11.44:1.

Should I use black or white text on #b9bfd1?

Black. It scores 11.44:1 against #b9bfd1, versus 1.84:1 for white — AAA at any size.

Is #b9bfd1 accessible on a white background?

#b9bfd1 on white scores 1.84:1, which fails WCAG AA at every size. Darken it to #66739A to reach 4.5:1, or #4D5876 for 7:1.

What is the complementary color of #b9bfd1?

#D1CBB9 sits directly opposite on the wheel. Softer options are the split-complements #D1BFB9 and #CBD1B9, which give the same contrast with far less vibration.

What colors go well with #b9bfd1?

For interface work: #F6F7F9 as the surface, #CED2DF for borders, #5B678B for secondary text, #7F664D as an accent and #33394D for hover and pressed states. For a palette, the analogous pair #B9CBD1 and #BFB9D1 stays calm, while #D1CBB9 is the loudest partner.

What is #b9bfd1 in CMYK for printing?

cmyk(12%, 9%, 0%, 18%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b9bfd1 warm or cool?

Cool — it scores 75 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #BCB9D1; nudged cooler, #B8C4D2.

Which Tailwind color is closest to #b9bfd1?

The sky family — its 500 step is #0ea5e9, ΔE2000 23.4 away. That is a visible difference, so define #b9bfd1 as a custom token rather than reaching for the built-in.

How do I use #b9bfd1 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b9bfd1] or text-[#b9bfd1], 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 #b9bfd1 with 50% opacity?

rgba(185, 191, 209, 0.5), or #b9bfd180 in eight-digit hex. Over white that composites to #DCDFE8; over black, #5D6069.

Is #b9bfd1 a web-safe color?

No. The nearest web-safe colour is #CCCCCC, ΔE2000 8.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #b9bfd1 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 moderate chroma the association is present but not shouted.

What gradient works with #b9bfd1?
