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 #ac9fdc

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 #2F225D
Safe as a 1px border on white
No — use #9988D4

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 #ac9fdc 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.

#ac9fdc, answered

What color is #ac9fdc?

#ac9fdc is a light vivid blue, closest to Plum (ΔE2000 11.7). It sits at 253° on the hue wheel with 47% saturation and 74% lightness, which reads as cool.

What is the RGB value of #ac9fdc?

rgb(172, 159, 220) — 172 red, 159 green and 220 blue out of 255, or 67.5% / 62.4% / 86.3% by channel.

What is #ac9fdc in HSL and HSV?

hsl(253, 47%, 74%) and hsv(253, 28%, 86%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ac9fdc a light or a dark color?

It is a mid-tone. Relative luminance is 0.3873 and perceived brightness is 67%, so black text on it reaches 8.75:1.

Should I use black or white text on #ac9fdc?

Black. It scores 8.75:1 against #ac9fdc, versus 2.40:1 for white — AAA at any size.

Is #ac9fdc accessible on a white background?

#ac9fdc on white scores 2.40:1, which fails WCAG AA at every size. Darken it to #7B67C8 to reach 4.5:1, or #5C43B8 for 7:1.

What is the complementary color of #ac9fdc?

#CFDC9F sits directly opposite on the wheel. Softer options are the split-complements #DCCA9F and #B0DC9F, which give the same contrast with far less vibration.

What colors go well with #ac9fdc?

For interface work: #F6F4FA as the surface, #CBC3E9 for borders, #5C4B9B for secondary text, #9A9532 as an accent and #2F225D for hover and pressed states. For a palette, the analogous pair #9FB0DC and #CA9FDC stays calm, while #CFDC9F is the loudest partner.

What is #ac9fdc in CMYK for printing?

cmyk(22%, 28%, 0%, 14%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #ac9fdc warm or cool?

Cool — it scores 76 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C29FDC; nudged cooler, #9EA7DD.

Which Tailwind color is closest to #ac9fdc?

The purple family — its 500 step is #a855f7, ΔE2000 20.2 away. That is a visible difference, so define #ac9fdc as a custom token rather than reaching for the built-in.

How do I use #ac9fdc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ac9fdc] or text-[#ac9fdc], 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 #ac9fdc with 50% opacity?

rgba(172, 159, 220, 0.5), or #ac9fdc80 in eight-digit hex. Over white that composites to #D6CFEE; over black, #56506E.

Is #ac9fdc a web-safe color?

No. The nearest web-safe colour is #9999CC, ΔE2000 4.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #ac9fdc 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 #ac9fdc?

The safest is same-hue elevation: linear-gradient(135deg, #D3CCEC, #ac9fdc 45%, #2F225D). For more colour, a short hue run to #D188D4 keeps it rich without turning muddy.
