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 #abbbcb

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 #31404F
Safe as a 1px border on white
No — use #7F97B0

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.

#abbbcb, answered

What color is #abbbcb?

#abbbcb is a light soft blue, closest to Light Steel Blue (ΔE2000 4.3). It sits at 210° on the hue wheel with 24% saturation and 73% lightness, which reads as cool.

What is the RGB value of #abbbcb?

rgb(171, 187, 203) — 171 red, 187 green and 203 blue out of 255, or 67.1% / 73.3% / 79.6% by channel.

What is #abbbcb in HSL and HSV?

hsl(210, 24%, 73%) and hsv(210, 16%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #abbbcb a light or a dark color?

It is a mid-tone. Relative luminance is 0.4851 and perceived brightness is 72%, so black text on it reaches 10.70:1.

Should I use black or white text on #abbbcb?

Black. It scores 10.70:1 against #abbbcb, versus 1.96:1 for white — AAA at any size.

Is #abbbcb accessible on a white background?

#abbbcb on white scores 1.96:1, which fails WCAG AA at every size. Darken it to #5C7995 to reach 4.5:1, or #455A6F for 7:1.

What is the complementary color of #abbbcb?

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

What colors go well with #abbbcb?

For interface work: #F6F7F9 as the surface, #CDD6E0 for borders, #58738E for secondary text, #82594A as an accent and #31404F for hover and pressed states. For a palette, the analogous pair #ABCBCB and #ABABCB stays calm, while #CBBBAB is the loudest partner.

What is #abbbcb in CMYK for printing?

cmyk(16%, 8%, 0%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #abbbcb warm or cool?

Cool — it scores 84 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #ABAFCB; nudged cooler, #9AADC3.

Which Tailwind color is closest to #abbbcb?

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

How do I use #abbbcb in Tailwind CSS?

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

rgba(171, 187, 203, 0.5), or #abbbcb80 in eight-digit hex. Over white that composites to #D5DDE5; over black, #565E66.

Is #abbbcb a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 14.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #abbbcb 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 #abbbcb?

The safest is same-hue elevation: linear-gradient(135deg, #D1DAE2, #abbbcb 45%, #31404F). For more colour, a short hue run to #A298BF keeps it rich without turning muddy.
