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 #b7becf

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 #333A4D
Safe as a 1px border on white
No — use #8995B0

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.

#b7becf, answered

What color is #b7becf?

#b7becf is a light soft blue, closest to Light Steel Blue (ΔE2000 5). It sits at 223° on the hue wheel with 20% saturation and 77% lightness, which reads as cool.

What is the RGB value of #b7becf?

rgb(183, 190, 207) — 183 red, 190 green and 207 blue out of 255, or 71.8% / 74.5% / 81.2% by channel.

What is #b7becf in HSL and HSV?

hsl(223, 20%, 77%) and hsv(223, 12%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b7becf a light or a dark color?

It is a light color. Relative luminance is 0.5140 and perceived brightness is 74%, so black text on it reaches 11.28:1.

Should I use black or white text on #b7becf?

Black. It scores 11.28:1 against #b7becf, versus 1.86:1 for white — AAA at any size.

Is #b7becf accessible on a white background?

#b7becf on white scores 1.86:1, which fails WCAG AA at every size. Darken it to #68769A to reach 4.5:1, or #4D5873 for 7:1.

What is the complementary color of #b7becf?

#CFC8B7 sits directly opposite on the wheel. Softer options are the split-complements #CFBCB7 and #CACFB7, which give the same contrast with far less vibration.

What colors go well with #b7becf?

For interface work: #F6F7F9 as the surface, #CED3DE for borders, #5C698A for secondary text, #7E644E as an accent and #333A4D for hover and pressed states. For a palette, the analogous pair #B7CACF and #BCB7CF stays calm, while #CFC8B7 is the loudest partner.

What is #b7becf in CMYK for printing?

cmyk(12%, 8%, 0%, 19%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b7becf 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 #B9B7CF; nudged cooler, #B6C2D0.

Which Tailwind color is closest to #b7becf?

The cyan family — its 500 step is #06b6d4, ΔE2000 22.6 away. That is a visible difference, so define #b7becf as a custom token rather than reaching for the built-in.

How do I use #b7becf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b7becf] or text-[#b7becf], 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 #b7becf with 50% opacity?

rgba(183, 190, 207, 0.5), or #b7becf80 in eight-digit hex. Over white that composites to #DBDFE7; over black, #5C5F68.

Is #b7becf 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 #b7becf 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 #b7becf?

The safest is same-hue elevation: linear-gradient(135deg, #DCDFE8, #b7becf 45%, #333A4D). For more colour, a short hue run to #B3A5C3 keeps it rich without turning muddy.
