How to use #b2c7db

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 #294057
Safe as a 1px border on white
No — use #7097BC

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.

#b2c7db, answered

What color is #b2c7db?

#b2c7db is a light soft blue, closest to Light Steel Blue (ΔE2000 2.7). It sits at 209° on the hue wheel with 36% saturation and 78% lightness, which reads as cool.

What is the RGB value of #b2c7db?

rgb(178, 199, 219) — 178 red, 199 green and 219 blue out of 255, or 69.8% / 78% / 85.9% by channel.

What is #b2c7db in HSL and HSV?

hsl(209, 36%, 78%) and hsv(209, 19%, 86%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b2c7db a light or a dark color?

It is a light color. Relative luminance is 0.5543 and perceived brightness is 77%, so black text on it reaches 12.09:1.

Should I use black or white text on #b2c7db?

Black. It scores 12.09:1 against #b2c7db, versus 1.74:1 for white — AAA at any size.

Is #b2c7db accessible on a white background?

#b2c7db on white scores 1.74:1, which fails WCAG AA at every size. Darken it to #4C78A3 to reach 4.5:1, or #3A5C7C for 7:1.

What is the complementary color of #b2c7db?

#DBC6B2 sits directly opposite on the wheel. Softer options are the split-complements #DBB2B2 and #DBDAB2, which give the same contrast with far less vibration.

What colors go well with #b2c7db?

For interface work: #F5F7FA as the surface, #C7D7E5 for borders, #4B749B for secondary text, #8F4F3D as an accent and #294057 for hover and pressed states. For a palette, the analogous pair #B2DBDA and #B2B2DB stays calm, while #DBC6B2 is the loudest partner.

What is #b2c7db in CMYK for printing?

cmyk(19%, 9%, 0%, 14%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b2c7db warm or cool?

Cool — it scores 100 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B2B8DB; nudged cooler, #9FB8D4.

Which Tailwind color is closest to #b2c7db?

The cyan family — its 500 step is #06b6d4, ΔE2000 17.9 away. That is a visible difference, so define #b2c7db as a custom token rather than reaching for the built-in.

How do I use #b2c7db in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b2c7db] or text-[#b2c7db], 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 #b2c7db with 50% opacity?

rgba(178, 199, 219, 0.5), or #b2c7db80 in eight-digit hex. Over white that composites to #D9E3ED; over black, #59646E.

Is #b2c7db a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 13.7 away. The palette only matters for legacy displays and some email clients now.
