  • Brand accents, badges and data highlights
Use with care
  • Text on black or near-black surfaces
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • 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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The low lightness adds weight and formality.

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 #360d72 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.

#360d72, answered

What color is #360d72?

#360d72 is a deep electric violet, closest to Indigo (ΔE2000 4.1). It sits at 264° on the hue wheel with 80% saturation and 25% lightness, which reads as cool.

What is the RGB value of #360d72?

rgb(54, 13, 114) — 54 red, 13 green and 114 blue out of 255, or 21.2% / 5.1% / 44.7% by channel.

What is #360d72 in HSL and HSV?

hsl(264, 80%, 25%) and hsv(264, 89%, 45%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #360d72 a light or a dark color?

It is a dark color. Relative luminance is 0.0229 and perceived brightness is 19%, so white text on it reaches 14.41:1.

Should I use black or white text on #360d72?

White. It scores 14.41:1 against #360d72, versus 1.46:1 for black — AAA at any size.

Is #360d72 accessible on a white background?

#360d72 on white scores 14.41:1, which clears AAA at every size.

What is the complementary color of #360d72?

#49720D sits directly opposite on the wheel. Softer options are the split-complements #72690D and #16720D, which give the same contrast with far less vibration.

What colors go well with #360d72?

For interface work: #F7F4FA as the surface, #D2C0ED for borders, #6B4B9B for secondary text, #64750A as an accent and #360D72 for hover and pressed states. For a palette, the analogous pair #0D1672 and #690D72 stays calm, while #49720D is the loudest partner.

What is #360d72 in CMYK for printing?

cmyk(53%, 89%, 0%, 55%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #360d72 warm or cool?

Cool — it scores 70 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #5B0D72; nudged cooler, #100C73.

Which Tailwind color is closest to #360d72?

The indigo family — its 500 step is #6366f1, ΔE2000 28.8 away. That is a visible difference, so define #360d72 as a custom token rather than reaching for the built-in.

How do I use #360d72 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#360d72] or text-[#360d72], 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 #360d72 with 50% opacity?

rgba(54, 13, 114, 0.5), or #360d7280 in eight-digit hex. Over white that composites to #9B86B9; over black, #1B0739.

Is #360d72 a web-safe color?
