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.

  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Full-page backgrounds — tiring over long sessions
  • Pairing with a same-lightness hue — edges vibrate

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 mid lightness keeps it versatile in both themes.

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 #a840cd 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.

#a840cd, answered

What color is #a840cd?

#a840cd is a balanced vivid violet, closest to Dark Orchid (ΔE2000 4.4). It sits at 284° on the hue wheel with 59% saturation and 53% lightness, which reads as cool.

What is the RGB value of #a840cd?

rgb(168, 64, 205) — 168 red, 64 green and 205 blue out of 255, or 65.9% / 25.1% / 80.4% by channel.

What is #a840cd in HSL and HSV?

hsl(284, 59%, 53%) and hsv(284, 69%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a840cd a light or a dark color?

It is a dark color. Relative luminance is 0.1640 and perceived brightness is 49%, so white text on it reaches 4.91:1.

Should I use black or white text on #a840cd?

White. It scores 4.91:1 against #a840cd, versus 4.28:1 for black — AA at any size.

Is #a840cd accessible on a white background?

#a840cd on white scores 4.91:1, which clears AA at every size but not AAA.

What is the complementary color of #a840cd?

#65CD40 sits directly opposite on the wheel. Softer options are the split-complements #ABCD40 and #40CD61, which give the same contrast with far less vibration.

What colors go well with #a840cd?

For interface work: #F9F4FA as the surface, #E1C0ED for borders, #864B9B for secondary text, #67A626 as an accent and #521A65 for hover and pressed states. For a palette, the analogous pair #6140CD and #CD40AB stays calm, while #65CD40 is the loudest partner.

What is #a840cd in CMYK for printing?

cmyk(18%, 69%, 0%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a840cd warm or cool?

Cool — it scores 59 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CD40BE; nudged cooler, #743DCF.

Which Tailwind color is closest to #a840cd?

The purple family — its 500 step is #a855f7, ΔE2000 8 away. That is a visible difference, so define #a840cd as a custom token rather than reaching for the built-in.

How do I use #a840cd in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a840cd] or text-[#a840cd], 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 #a840cd with 50% opacity?

rgba(168, 64, 205, 0.5), or #a840cd80 in eight-digit hex. Over white that composites to #D4A0E6; over black, #542067.

Is #a840cd a web-safe color?

No. The nearest web-safe colour is #9933CC, ΔE2000 4.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #a840cd mean?

As a violet, it reads creative, premium, modern. 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. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #a840cd?
