How to use #877abc

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
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Small text on white — under 4.5:1
  • 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 #332B55
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.

trustedcalmcompetentcorporate

The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The mid lightness keeps it versatile in both themes.

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 #877abc 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.

#877abc, answered

What color is #877abc?

#877abc is a balanced soft blue, closest to Medium Purple (ΔE2000 7.1). It sits at 252° on the hue wheel with 33% saturation and 61% lightness, which reads as cool.

What is the RGB value of #877abc?

rgb(135, 122, 188) — 135 red, 122 green and 188 blue out of 255, or 52.9% / 47.8% / 73.7% by channel.

What is #877abc in HSL and HSV?

hsl(252, 33%, 61%) and hsv(252, 35%, 74%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #877abc a light or a dark color?

It is a mid-tone. Relative luminance is 0.2270 and perceived brightness is 53%, so black text on it reaches 5.54:1.

Should I use black or white text on #877abc?

Black. It scores 5.54:1 against #877abc, versus 3.79:1 for white — AA at any size.

Is #877abc accessible on a white background?

#877abc on white scores 3.79:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #7B6CB5 to reach 4.5:1, or #5B4D98 for 7:1.

What is the complementary color of #877abc?

#AFBC7A sits directly opposite on the wheel. Softer options are the split-complements #BCA87A and #8EBC7A, which give the same contrast with far less vibration.

What colors go well with #877abc?

For interface work: #F6F5FA as the surface, #CEC9E4 for borders, #5C4D99 for secondary text, #8C8840 as an accent and #332B55 for hover and pressed states. For a palette, the analogous pair #7A8EBC and #A87ABC stays calm, while #AFBC7A is the loudest partner.

What is #877abc in CMYK for printing?

cmyk(28%, 35%, 0%, 26%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #877abc warm or cool?

Cool — it scores 75 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #9F7ABC; nudged cooler, #7884BE.

Which Tailwind color is closest to #877abc?

The slate family — its 500 step is #64748b, ΔE2000 12.4 away. That is a visible difference, so define #877abc as a custom token rather than reaching for the built-in.

How do I use #877abc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#877abc] or text-[#877abc], 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 #877abc with 50% opacity?

rgba(135, 122, 188, 0.5), or #877abc80 in eight-digit hex. Over white that composites to #C3BDDE; over black, #443D5E.

Is #877abc a web-safe color?

No. The nearest web-safe colour is #9966CC, ΔE2000 8.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #877abc 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 moderate chroma the association is present but not shouted.

What gradient works with #877abc?
