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 #b8dfff

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 #004680
Safe as a 1px border on white
No — use #1A98FF

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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.

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.

#b8dfff, answered

What color is #b8dfff?

#b8dfff is a pale electric blue, closest to Light Sky Blue (ΔE2000 7.3). It sits at 207° on the hue wheel with 100% saturation and 86% lightness, which reads as cool.

What is the RGB value of #b8dfff?

rgb(184, 223, 255) — 184 red, 223 green and 255 blue out of 255, or 72.2% / 87.5% / 100% by channel.

What is #b8dfff in HSL and HSV?

hsl(207, 100%, 86%) and hsv(207, 28%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b8dfff a light or a dark color?

It is a light color. Relative luminance is 0.7019 and perceived brightness is 85%, so black text on it reaches 15.04:1.

Should I use black or white text on #b8dfff?

Black. It scores 15.04:1 against #b8dfff, versus 1.40:1 for white — AAA at any size.

Is #b8dfff accessible on a white background?

#b8dfff on white scores 1.40:1, which fails WCAG AA at every size. Darken it to #0076D7 to reach 4.5:1, or #005AA4 for 7:1.

What is the complementary color of #b8dfff?

#FFD8B8 sits directly opposite on the wheel. Softer options are the split-complements #FFB8BC and #FFFBB8, which give the same contrast with far less vibration.

What colors go well with #b8dfff?

For interface work: #F4F8FA as the surface, #C0D8ED for borders, #4B779B for secondary text, #CC2800 as an accent and #004680 for hover and pressed states. For a palette, the analogous pair #B8FFFB and #B8BCFF stays calm, while #FFD8B8 is the loudest partner.

What is #b8dfff in CMYK for printing?

cmyk(28%, 13%, 0%, 0%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #b8dfff warm or cool?

Cool — it scores 99 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B8C5FF; nudged cooler, #9FCEFF.

Which Tailwind color is closest to #b8dfff?

The cyan family — its 500 step is #06b6d4, ΔE2000 18.4 away. That is a visible difference, so define #b8dfff as a custom token rather than reaching for the built-in.

How do I use #b8dfff in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b8dfff] or text-[#b8dfff], 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 #b8dfff with 50% opacity?

rgba(184, 223, 255, 0.5), or #b8dfff80 in eight-digit hex. Over white that composites to #DCEFFF; over black, #5C7080.

Is #b8dfff a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 13.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #b8dfff 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 #b8dfff?
