How to use #b577d7

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

Works well for
  • Headings from 24px up on white
  • 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
  • Small text on white — under 4.5:1
  • 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
24px / 18.66px bold
Safe as a fill behind white type
No — use #4A1D62
Safe as a 1px border on white
Yes

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 #b577d7 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.

#b577d7, answered

What color is #b577d7?

#b577d7 is a light vivid violet, closest to Orchid (ΔE2000 7.3). It sits at 279° on the hue wheel with 55% saturation and 66% lightness, which reads as cool.

What is the RGB value of #b577d7?

rgb(181, 119, 215) — 181 red, 119 green and 215 blue out of 255, or 71% / 46.7% / 84.3% by channel.

What is #b577d7 in HSL and HSV?

hsl(279, 55%, 66%) and hsv(279, 45%, 84%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b577d7 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2792 and perceived brightness is 60%, so black text on it reaches 6.58:1.

Should I use black or white text on #b577d7?

Black. It scores 6.58:1 against #b577d7, versus 3.19:1 for white — AA at any size.

Is #b577d7 accessible on a white background?

#b577d7 on white scores 3.19:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #A050CB to reach 4.5:1, or #8132AB for 7:1.

What is the complementary color of #b577d7?

#99D777 sits directly opposite on the wheel. Softer options are the split-complements #C9D777 and #77D785, which give the same contrast with far less vibration.

What colors go well with #b577d7?

For interface work: #F8F4FA as the surface, #DDC0EC for borders, #7F4B9B for secondary text, #73A12B as an accent and #4A1D62 for hover and pressed states. For a palette, the analogous pair #8577D7 and #D777C9 stays calm, while #99D777 is the loudest partner.

What is #b577d7 in CMYK for printing?

cmyk(16%, 45%, 0%, 16%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b577d7 warm or cool?

Cool — it scores 62 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D777D6; nudged cooler, #9175D9.

Which Tailwind color is closest to #b577d7?

The fuchsia family — its 500 step is #d946ef, ΔE2000 9.9 away. That is a visible difference, so define #b577d7 as a custom token rather than reaching for the built-in.

How do I use #b577d7 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b577d7] or text-[#b577d7], 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 #b577d7 with 50% opacity?
