How to use #b5a5df

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 #32215E
Safe as a 1px border on white
No — use #9C87D4

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

creativepremiummodernimaginative

Violet sits between the warmth of red and the calm of blue, so it reads as inventive without reading as risky. Current shorthand for software craft.

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

Deep violets swallow detail on screens with poor gamma; check it on a cheap laptop panel.

Transparency

What each alpha value actually composites to. The top row is #b5a5df 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.

#b5a5df, answered

What color is #b5a5df?

#b5a5df is a light vivid violet, closest to Plum (ΔE2000 10.3). It sits at 257° on the hue wheel with 48% saturation and 76% lightness, which reads as cool.

What is the RGB value of #b5a5df?

rgb(181, 165, 223) — 181 red, 165 green and 223 blue out of 255, or 71% / 64.7% / 87.5% by channel.

What is #b5a5df in HSL and HSV?

hsl(257, 48%, 76%) and hsv(257, 26%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b5a5df a light or a dark color?

It is a mid-tone. Relative luminance is 0.4206 and perceived brightness is 70%, so black text on it reaches 9.41:1.

Should I use black or white text on #b5a5df?

Black. It scores 9.41:1 against #b5a5df, versus 2.23:1 for white — AAA at any size.

Is #b5a5df accessible on a white background?

#b5a5df on white scores 2.23:1, which fails WCAG AA at every size. Darken it to #8165C8 to reach 4.5:1, or #6140B5 for 7:1.

What is the complementary color of #b5a5df?

#CFDFA5 sits directly opposite on the wheel. Softer options are the split-complements #DFD2A5 and #B2DFA5, which give the same contrast with far less vibration.

What colors go well with #b5a5df?

For interface work: #F6F4FA as the surface, #CEC3EA for borders, #614B9B for secondary text, #989A32 as an accent and #32215E for hover and pressed states. For a palette, the analogous pair #A5B2DF and #D2A5DF stays calm, while #CFDFA5 is the loudest partner.

What is #b5a5df in CMYK for printing?

cmyk(19%, 26%, 0%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b5a5df warm or cool?

Cool — it scores 74 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CAA5DF; nudged cooler, #A4A9E0.

Which Tailwind color is closest to #b5a5df?

The purple family — its 500 step is #a855f7, ΔE2000 21.7 away. That is a visible difference, so define #b5a5df as a custom token rather than reaching for the built-in.

How do I use #b5a5df in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b5a5df] or text-[#b5a5df], 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 #b5a5df with 50% opacity?

rgba(181, 165, 223, 0.5), or #b5a5df80 in eight-digit hex. Over white that composites to #DAD2EF; over black, #5B5370.

Is #b5a5df a web-safe color?

No. The nearest web-safe colour is #CC99CC, ΔE2000 9.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #b5a5df mean?
