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.

Color scale — 50 to 950

A Tailwind-shaped ramp built around this exact hex. #2d103b is pinned to step 950; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.

  • Headers, footers and dark-mode surfaces
  • 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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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.

#2d103b, answered

What color is #2d103b?

#2d103b is a deep vivid violet, closest to Midnight Blue (ΔE2000 12.9). It sits at 281° on the hue wheel with 57% saturation and 15% lightness, which reads as cool.

What is the RGB value of #2d103b?

rgb(45, 16, 59) — 45 red, 16 green and 59 blue out of 255, or 17.6% / 6.3% / 23.1% by channel.

What is #2d103b in HSL and HSV?

hsl(281, 57%, 15%) and hsv(280, 73%, 23%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2d103b a light or a dark color?

It is a dark color. Relative luminance is 0.0124 and perceived brightness is 13%, so white text on it reaches 16.82:1.

Should I use black or white text on #2d103b?

White. It scores 16.82:1 against #2d103b, versus 1.25:1 for black — AAA at any size.

Is #2d103b accessible on a white background?

#2d103b on white scores 16.82:1, which clears AAA at every size.

What is the complementary color of #2d103b?

#1E3B10 sits directly opposite on the wheel. Softer options are the split-complements #333B10 and #103B18, which give the same contrast with far less vibration.

What colors go well with #2d103b?

For interface work: #F8F4FA as the surface, #DEC0ED for borders, #814B9B for secondary text, #293C0F as an accent and #4D1B64 for hover and pressed states. For a palette, the analogous pair #18103B and #3B1033 stays calm, while #1E3B10 is the loudest partner.

What is #2d103b in CMYK for printing?

cmyk(24%, 73%, 0%, 77%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #2d103b 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 #3B1039; nudged cooler, #1D0F3C.

Which Tailwind color is closest to #2d103b?

The gray family — its 500 step is #6b7280, ΔE2000 33.1 away. That is a visible difference, so define #2d103b as a custom token rather than reaching for the built-in.

How do I use #2d103b in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2d103b] or text-[#2d103b], 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 #2d103b with 50% opacity?

rgba(45, 16, 59, 0.5), or #2d103b80 in eight-digit hex. Over white that composites to #96889D; over black, #17081E.

Is #2d103b a web-safe color?

No. The nearest web-safe colour is #330033, ΔE2000 4.8 away. The palette only matters for legacy displays and some email clients now.
