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 #b8bdfa

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 #081177
Safe as a 1px border on white
No — use #7F88F6

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.

Transparency

What each alpha value actually composites to. The top row is #b8bdfa 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.

#b8bdfa, answered

What color is #b8bdfa?

#b8bdfa is a pale electric blue, closest to Light Steel Blue (ΔE2000 8.5). It sits at 236° on the hue wheel with 87% saturation and 85% lightness, which reads as cool.

What is the RGB value of #b8bdfa?

rgb(184, 189, 250) — 184 red, 189 green and 250 blue out of 255, or 72.2% / 74.1% / 98% by channel.

What is #b8bdfa in HSL and HSV?

hsl(236, 87%, 85%) and hsv(235, 26%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b8bdfa a light or a dark color?

It is a light color. Relative luminance is 0.5349 and perceived brightness is 77%, so black text on it reaches 11.70:1.

Should I use black or white text on #b8bdfa?

Black. It scores 11.70:1 against #b8bdfa, versus 1.80:1 for white — AAA at any size.

Is #b8bdfa accessible on a white background?

#b8bdfa on white scores 1.80:1, which fails WCAG AA at every size. Darken it to #5964F3 to reach 4.5:1, or #2938F0 for 7:1.

What is the complementary color of #b8bdfa?

#FAF5B8 sits directly opposite on the wheel. Softer options are the split-complements #FAD4B8 and #DEFAB8, which give the same contrast with far less vibration.

What colors go well with #b8bdfa?

For interface work: #F4F5FA as the surface, #C0C3ED for borders, #4B519B for secondary text, #C48508 as an accent and #081177 for hover and pressed states. For a palette, the analogous pair #B8DEFA and #D4B8FA stays calm, while #FAF5B8 is the loudest partner.

What is #b8bdfa in CMYK for printing?

cmyk(26%, 24%, 0%, 2%). 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 #b8bdfa warm or cool?

Cool — it scores 86 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CBB8FA; nudged cooler, #B7D0FB.

Which Tailwind color is closest to #b8bdfa?

The blue family — its 500 step is #3b82f6, ΔE2000 22.3 away. That is a visible difference, so define #b8bdfa as a custom token rather than reaching for the built-in.

How do I use #b8bdfa in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b8bdfa] or text-[#b8bdfa], 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 #b8bdfa with 50% opacity?

rgba(184, 189, 250, 0.5), or #b8bdfa80 in eight-digit hex. Over white that composites to #DCDEFD; over black, #5C5F7D.

Is #b8bdfa a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 4.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #b8bdfa 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 #b8bdfa?
