How to use #cbd8eb

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 #233A5C
Safe as a 1px border on white
No — use #7396C9

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 high lightness makes it recede — a surface colour rather than a statement.

Worth knowing

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

#cbd8eb, answered

What color is #cbd8eb?

#cbd8eb is a pale soft blue, closest to Light Steel Blue (ΔE2000 5.8). It sits at 216° on the hue wheel with 44% saturation and 86% lightness, which reads as cool.

What is the RGB value of #cbd8eb?

rgb(203, 216, 235) — 203 red, 216 green and 235 blue out of 255, or 79.6% / 84.7% / 92.2% by channel.

What is #cbd8eb in HSL and HSV?

hsl(216, 44%, 86%) and hsv(216, 14%, 92%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cbd8eb a light or a dark color?

It is a light color. Relative luminance is 0.6781 and perceived brightness is 84%, so black text on it reaches 14.56:1.

Should I use black or white text on #cbd8eb?

Black. It scores 14.56:1 against #cbd8eb, versus 1.44:1 for white — AAA at any size.

Is #cbd8eb accessible on a white background?

#cbd8eb on white scores 1.44:1, which fails WCAG AA at every size. Darken it to #4A77B9 to reach 4.5:1, or #36598C for 7:1.

What is the complementary color of #cbd8eb?

#EBDECB sits directly opposite on the wheel. Softer options are the split-complements #EBCECB and #E8EBCB, which give the same contrast with far less vibration.

What colors go well with #cbd8eb?

For interface work: #F4F7FA as the surface, #C4D3E8 for borders, #4B6B9B for secondary text, #965836 as an accent and #233A5C for hover and pressed states. For a palette, the analogous pair #CBE8EB and #CECBEB stays calm, while #EBDECB is the loudest partner.

What is #cbd8eb in CMYK for printing?

cmyk(14%, 8%, 0%, 8%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #cbd8eb warm or cool?

Cool — it scores 97 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CBCCEB; nudged cooler, #B8CDE5.

Which Tailwind color is closest to #cbd8eb?

The cyan family — its 500 step is #06b6d4, ΔE2000 22.6 away. That is a visible difference, so define #cbd8eb as a custom token rather than reaching for the built-in.

How do I use #cbd8eb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cbd8eb] or text-[#cbd8eb], 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 #cbd8eb with 50% opacity?

rgba(203, 216, 235, 0.5), or #cbd8eb80 in eight-digit hex. Over white that composites to #E5ECF5; over black, #666C76.

Is #cbd8eb a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 10.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #cbd8eb 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 #cbd8eb?

The safest is same-hue elevation: linear-gradient(135deg, #F0F4F9, #cbd8eb 45%, #233A5C). For more colour, a short hue run to #C5B5E3 keeps it rich without turning muddy.
