How to use #9eb9cd

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 #2B4354
Safe as a 1px border on white
No — use #6F97B5

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.

Transparency

What each alpha value actually composites to. The top row is #9eb9cd 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.

#9eb9cd, answered

What color is #9eb9cd?

#9eb9cd is a light soft blue, closest to Light Steel Blue (ΔE2000 5.3). It sits at 206° on the hue wheel with 32% saturation and 71% lightness, which reads as cool.

What is the RGB value of #9eb9cd?

rgb(158, 185, 205) — 158 red, 185 green and 205 blue out of 255, or 62% / 72.5% / 80.4% by channel.

What is #9eb9cd in HSL and HSV?

hsl(206, 32%, 71%) and hsv(206, 23%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #9eb9cd a light or a dark color?

It is a mid-tone. Relative luminance is 0.4637 and perceived brightness is 71%, so black text on it reaches 10.27:1.

Should I use black or white text on #9eb9cd?

Black. It scores 10.27:1 against #9eb9cd, versus 2.04:1 for white — AAA at any size.

Is #9eb9cd accessible on a white background?

#9eb9cd on white scores 2.04:1, which fails WCAG AA at every size. Darken it to #507B9C to reach 4.5:1, or #3B5B73 for 7:1.

What is the complementary color of #9eb9cd?

#CDB29E sits directly opposite on the wheel. Softer options are the split-complements #CD9EA2 and #CDCA9E, which give the same contrast with far less vibration.

What colors go well with #9eb9cd?

For interface work: #F5F8FA as the surface, #C9D8E3 for borders, #4E7897 for secondary text, #8B4E41 as an accent and #2B4354 for hover and pressed states. For a palette, the analogous pair #9ECDCA and #9EA2CD stays calm, while #CDB29E is the loudest partner.

What is #9eb9cd in CMYK for printing?

cmyk(23%, 10%, 0%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #9eb9cd warm or cool?

Cool — it scores 94 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #9EA8CD; nudged cooler, #8CA8C6.

Which Tailwind color is closest to #9eb9cd?

The cyan family — its 500 step is #06b6d4, ΔE2000 14.7 away. That is a visible difference, so define #9eb9cd as a custom token rather than reaching for the built-in.

How do I use #9eb9cd in Tailwind CSS?

Inline it as an arbitrary value with bg-[#9eb9cd] or text-[#9eb9cd], 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 #9eb9cd with 50% opacity?

rgba(158, 185, 205, 0.5), or #9eb9cd80 in eight-digit hex. Over white that composites to #CFDCE6; over black, #4F5D67.

Is #9eb9cd a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 12.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #9eb9cd 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 #9eb9cd?
