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.

How to use #df0413

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
Minimum size as text on white

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 #df0413 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.

#df0413, answered

What color is #df0413?

#df0413 is a dark electric red, closest to Red (ΔE2000 7.3). It sits at 356° on the hue wheel with 97% saturation and 45% lightness, which reads as warm.

What is the RGB value of #df0413?

rgb(223, 4, 19) — 223 red, 4 green and 19 blue out of 255, or 87.5% / 1.6% / 7.5% by channel.

What is #df0413 in HSL and HSV?

hsl(356, 97%, 45%) and hsv(356, 98%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #df0413 a light or a dark color?

It is a dark color. Relative luminance is 0.1582 and perceived brightness is 48%, so white text on it reaches 5.04:1.

Should I use black or white text on #df0413?

White. It scores 5.04:1 against #df0413, versus 4.16:1 for black — AA at any size.

Is #df0413 accessible on a white background?

#df0413 on white scores 5.04:1, which clears AA at every size but not AAA.

What is the complementary color of #df0413?

#04DFD0 sits directly opposite on the wheel. Softer options are the split-complements #04DF63 and #0480DF, which give the same contrast with far less vibration.

What colors go well with #df0413?

For interface work: #FAF4F5 as the surface, #EDC0C3 for borders, #9B4B50 for secondary text, #00CC8B as an accent and #7D020B for hover and pressed states. For a palette, the analogous pair #DF0480 and #DF6304 stays calm, while #04DFD0 is the loudest partner.

What is #df0413 in CMYK for printing?

cmyk(0%, 98%, 92%, 13%). 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 #df0413 warm or cool?

Warm — it scores 19 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DF2E04; nudged cooler, #E10263.

Which Tailwind color is closest to #df0413?

The red family — its 500 step is #ef4444, ΔE2000 9.9 away. That is a visible difference, so define #df0413 as a custom token rather than reaching for the built-in.

How do I use #df0413 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#df0413] or text-[#df0413], 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 #df0413 with 50% opacity?

rgba(223, 4, 19, 0.5), or #df041380 in eight-digit hex. Over white that composites to #EF8289; over black, #70020A.

Is #df0413 a web-safe color?

No. The nearest web-safe colour is #CC0000, ΔE2000 4.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #df0413 mean?

As a red, it reads urgent, appetising, bold. 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 effect is amplified — it will dominate whatever sits beside it.

What gradient works with #df0413?
