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 #9ebfe0

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #1F4061
Safe as a 1px border on white
No — use #6499CE

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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 #9ebfe0 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.

#9ebfe0, answered

What color is #9ebfe0?

#9ebfe0 is a light vivid blue, closest to Light Steel Blue (ΔE2000 4.1). It sits at 210° on the hue wheel with 52% saturation and 75% lightness, which reads as cool.

What is the RGB value of #9ebfe0?

rgb(158, 191, 224) — 158 red, 191 green and 224 blue out of 255, or 62% / 74.9% / 87.8% by channel.

What is #9ebfe0 in HSL and HSV?

hsl(210, 52%, 75%) and hsv(210, 29%, 88%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #9ebfe0 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4991 and perceived brightness is 73%, so black text on it reaches 10.98:1.

Should I use black or white text on #9ebfe0?

Black. It scores 10.98:1 against #9ebfe0, versus 1.91:1 for white — AAA at any size.

Is #9ebfe0 accessible on a white background?

#9ebfe0 on white scores 1.91:1, which fails WCAG AA at every size. Darken it to #3B7AB9 to reach 4.5:1, or #2B5987 for 7:1.

What is the complementary color of #9ebfe0?

#E0BF9E sits directly opposite on the wheel. Softer options are the split-complements #E09E9E and #E0E09E, which give the same contrast with far less vibration.

What colors go well with #9ebfe0?

For interface work: #F4F7FA as the surface, #C1D6EB for borders, #4B739B for secondary text, #9F492D as an accent and #1F4061 for hover and pressed states. For a palette, the analogous pair #9EE0E0 and #9E9EE0 stays calm, while #E0BF9E is the loudest partner.

What is #9ebfe0 in CMYK for printing?

cmyk(30%, 15%, 0%, 12%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #9ebfe0 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 #9EA7E0; nudged cooler, #89B0DB.

Which Tailwind color is closest to #9ebfe0?

The sky family — its 500 step is #0ea5e9, ΔE2000 14.3 away. That is a visible difference, so define #9ebfe0 as a custom token rather than reaching for the built-in.

How do I use #9ebfe0 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#9ebfe0] or text-[#9ebfe0], 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 #9ebfe0 with 50% opacity?

rgba(158, 191, 224, 0.5), or #9ebfe080 in eight-digit hex. Over white that composites to #CFDFF0; over black, #4F6070.

Is #9ebfe0 a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 15.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #9ebfe0 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 chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #9ebfe0?
