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 #b3afee

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 #1C1669
Safe as a 1px border on white
No — use #8F89E6

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 #b3afee 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.

#b3afee, answered

What color is #b3afee?

#b3afee is a light vivid blue, closest to Light Steel Blue (ΔE2000 10.3). It sits at 244° on the hue wheel with 65% saturation and 81% lightness, which reads as cool.

What is the RGB value of #b3afee?

rgb(179, 175, 238) — 179 red, 175 green and 238 blue out of 255, or 70.2% / 68.6% / 93.3% by channel.

What is #b3afee in HSL and HSV?

hsl(244, 65%, 81%) and hsv(244, 26%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b3afee a light or a dark color?

It is a mid-tone. Relative luminance is 0.4642 and perceived brightness is 72%, so black text on it reaches 10.28:1.

Should I use black or white text on #b3afee?

Black. It scores 10.28:1 against #b3afee, versus 2.04:1 for white — AAA at any size.

Is #b3afee accessible on a white background?

#b3afee on white scores 2.04:1, which fails WCAG AA at every size. Darken it to #6B63DE to reach 4.5:1, or #473ED6 for 7:1.

What is the complementary color of #b3afee?

#EAEEAF sits directly opposite on the wheel. Softer options are the split-complements #EED3AF and #CBEEAF, which give the same contrast with far less vibration.

What colors go well with #b3afee?

For interface work: #F5F4FA as the surface, #C3C0ED for borders, #504B9B for secondary text, #AC9120 as an accent and #1C1669 for hover and pressed states. For a palette, the analogous pair #AFCBEE and #D3AFEE stays calm, while #EAEEAF is the loudest partner.

What is #b3afee in CMYK for printing?

cmyk(25%, 27%, 0%, 7%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b3afee warm or cool?

Cool — it scores 81 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CAAFEE; nudged cooler, #AEC2EF.

Which Tailwind color is closest to #b3afee?

The blue family — its 500 step is #3b82f6, ΔE2000 21.4 away. That is a visible difference, so define #b3afee as a custom token rather than reaching for the built-in.

How do I use #b3afee in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b3afee] or text-[#b3afee], 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 #b3afee with 50% opacity?

rgba(179, 175, 238, 0.5), or #b3afee80 in eight-digit hex. Over white that composites to #D9D7F7; over black, #5A5877.

Is #b3afee a web-safe color?

No. The nearest web-safe colour is #CC99FF, ΔE2000 10.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #b3afee 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 #b3afee?
