How to use #d80c39

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Body text and links on white
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • Status meaning — pair it with an icon or label, never colour alone
  • 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.

urgentappetisingboldphysical

Red arrives before the rest of the page does. It raises attention and appetite, which is why it runs food, sport and clearance pricing.

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

It is also the universal error colour. Use it as a brand accent and users may read a warning that is not there.

What each alpha value actually composites to. The top row is #d80c39 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.

#d80c39, answered

What color is #d80c39?

#d80c39 is a dark electric red, closest to Crimson (ΔE2000 1.2). It sits at 347° on the hue wheel with 90% saturation and 45% lightness, which reads as warm.

What is the RGB value of #d80c39?

rgb(216, 12, 57) — 216 red, 12 green and 57 blue out of 255, or 84.7% / 4.7% / 22.4% by channel.

What is #d80c39 in HSL and HSV?

hsl(347, 90%, 45%) and hsv(347, 94%, 85%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #d80c39 a light or a dark color?

It is a dark color. Relative luminance is 0.1516 and perceived brightness is 47%, so white text on it reaches 5.21:1.

Should I use black or white text on #d80c39?

White. It scores 5.21:1 against #d80c39, versus 4.03:1 for black — AA at any size.

Is #d80c39 accessible on a white background?

#d80c39 on white scores 5.21:1, which clears AA at every size but not AAA.

What is the complementary color of #d80c39?

#0CD8AB sits directly opposite on the wheel. Softer options are the split-complements #0CD845 and #0C9FD8, which give the same contrast with far less vibration.

What colors go well with #d80c39?

For interface work: #FAF4F6 as the surface, #EDC0CA for borders, #9B4B5C for secondary text, #06C66B as an accent and #790720 for hover and pressed states. For a palette, the analogous pair #D80C9F and #D8450C stays calm, while #0CD8AB is the loudest partner.

What is #d80c39 in CMYK for printing?

cmyk(0%, 94%, 74%, 15%). 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 #d80c39 warm or cool?

Warm — it scores 24 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D8280C; nudged cooler, #DA0A84.

Which Tailwind color is closest to #d80c39?

The red family — its 500 step is #ef4444, ΔE2000 9.9 away. That is a visible difference, so define #d80c39 as a custom token rather than reaching for the built-in.

How do I use #d80c39 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#d80c39] or text-[#d80c39], 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 #d80c39 with 50% opacity?

rgba(216, 12, 57, 0.5), or #d80c3980 in eight-digit hex. Over white that composites to #EC869C; over black, #6C061D.

Is #d80c39 a web-safe color?

No. The nearest web-safe colour is #CC0033, ΔE2000 2.8 away. The palette only matters for legacy displays and some email clients now.
