How to use #b0b5cd

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 #31364E
Safe as a 1px border on white
No — use #8A92B5

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.

What each alpha value actually composites to. The top row is #b0b5cd 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.

#b0b5cd, answered

What color is #b0b5cd?

#b0b5cd is a light soft blue, closest to Light Steel Blue (ΔE2000 6.9). It sits at 230° on the hue wheel with 23% saturation and 75% lightness, which reads as cool.

What is the RGB value of #b0b5cd?

rgb(176, 181, 205) — 176 red, 181 green and 205 blue out of 255, or 69% / 71% / 80.4% by channel.

What is #b0b5cd in HSL and HSV?

hsl(230, 23%, 75%) and hsv(230, 14%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b0b5cd a light or a dark color?

It is a mid-tone. Relative luminance is 0.4669 and perceived brightness is 72%, so black text on it reaches 10.34:1.

Should I use black or white text on #b0b5cd?

Black. It scores 10.34:1 against #b0b5cd, versus 2.03:1 for white — AAA at any size.

Is #b0b5cd accessible on a white background?

#b0b5cd on white scores 2.03:1, which fails WCAG AA at every size. Darken it to #6872A0 to reach 4.5:1, or #4E567C for 7:1.

What is the complementary color of #b0b5cd?

#CDC8B0 sits directly opposite on the wheel. Softer options are the split-complements #CDBAB0 and #C3CDB0, which give the same contrast with far less vibration.

What colors go well with #b0b5cd?

For interface work: #F6F6F9 as the surface, #CDD0DF for borders, #59628D for secondary text, #826A4A as an accent and #31364E for hover and pressed states. For a palette, the analogous pair #B0C3CD and #BAB0CD stays calm, while #CDC8B0 is the loudest partner.

What is #b0b5cd in CMYK for printing?

cmyk(14%, 12%, 0%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b0b5cd 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 #B6B0CD; nudged cooler, #AFBCCE.

Which Tailwind color is closest to #b0b5cd?

The slate family — its 500 step is #64748b, ΔE2000 22.7 away. That is a visible difference, so define #b0b5cd as a custom token rather than reaching for the built-in.

How do I use #b0b5cd in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b0b5cd] or text-[#b0b5cd], 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 #b0b5cd with 50% opacity?

rgba(176, 181, 205, 0.5), or #b0b5cd80 in eight-digit hex. Over white that composites to #D8DAE6; over black, #585B67.

Is #b0b5cd a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 20.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #b0b5cd 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.
