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.

  • Text and icons on dark surfaces
  • 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 #a64cd3 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.

#a64cd3, answered

What color is #a64cd3?

#a64cd3 is a balanced vivid violet, closest to Medium Orchid (ΔE2000 5). It sits at 280° on the hue wheel with 61% saturation and 56% lightness, which reads as cool.

What is the RGB value of #a64cd3?

rgb(166, 76, 211) — 166 red, 76 green and 211 blue out of 255, or 65.1% / 29.8% / 82.7% by channel.

What is #a64cd3 in HSL and HSV?

hsl(280, 61%, 56%) and hsv(280, 64%, 83%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a64cd3 a light or a dark color?

It is a dark color. Relative luminance is 0.1798 and perceived brightness is 51%, so black text on it reaches 4.60:1.

Should I use black or white text on #a64cd3?

Black. It scores 4.60:1 against #a64cd3, versus 4.57:1 for white — AA at any size.

Is #a64cd3 accessible on a white background?

#a64cd3 on white scores 4.57:1, which clears AA at every size but not AAA.

What is the complementary color of #a64cd3?

#79D34C sits directly opposite on the wheel. Softer options are the split-complements #BDD34C and #4CD363, which give the same contrast with far less vibration.

What colors go well with #a64cd3?

For interface work: #F8F4FA as the surface, #DEC0ED for borders, #804B9B for secondary text, #71A725 as an accent and #4D1966 for hover and pressed states. For a palette, the analogous pair #634CD3 and #D34CBD stays calm, while #79D34C is the loudest partner.

What is #a64cd3 in CMYK for printing?

cmyk(21%, 64%, 0%, 17%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a64cd3 warm or cool?

Cool — it scores 61 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D34CCE; nudged cooler, #744AD5.

Which Tailwind color is closest to #a64cd3?

The purple family — its 500 step is #a855f7, ΔE2000 5.9 away. That is a visible difference, so define #a64cd3 as a custom token rather than reaching for the built-in.

How do I use #a64cd3 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a64cd3] or text-[#a64cd3], 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 #a64cd3 with 50% opacity?

rgba(166, 76, 211, 0.5), or #a64cd380 in eight-digit hex. Over white that composites to #D3A6E9; over black, #53266A.

Is #a64cd3 a web-safe color?

No. The nearest web-safe colour is #9933CC, ΔE2000 6 away. The palette only matters for legacy displays and some email clients now.

What does the color #a64cd3 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 #a64cd3?
