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 #df2e00

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

Works well for
  • Body text and links on white
  • Text and icons on dark surfaces
  • 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.

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.

#df2e00, answered

What color is #df2e00?

#df2e00 is a dark electric red, closest to Red (ΔE2000 5.7). It sits at 12° on the hue wheel with 100% saturation and 44% lightness, which reads as warm.

What is the RGB value of #df2e00?

rgb(223, 46, 0) — 223 red, 46 green and 0 blue out of 255, or 87.5% / 18% / 0% by channel.

What is #df2e00 in HSL and HSV?

hsl(12, 100%, 44%) and hsv(12, 100%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #df2e00 a light or a dark color?

It is a dark color. Relative luminance is 0.1764 and perceived brightness is 50%, so white text on it reaches 4.64:1.

Should I use black or white text on #df2e00?

White. It scores 4.64:1 against #df2e00, versus 4.53:1 for black — AA at any size.

Is #df2e00 accessible on a white background?

#df2e00 on white scores 4.64:1, which clears AA at every size but not AAA.

What is the complementary color of #df2e00?

#00B1DF sits directly opposite on the wheel. Softer options are the split-complements #00DF9D and #0041DF, which give the same contrast with far less vibration.

What colors go well with #df2e00?

For interface work: #FAF6F4 as the surface, #EDC9C0 for borders, #9B5B4B for secondary text, #00CCC3 as an accent and #801A00 for hover and pressed states. For a palette, the analogous pair #DF0041 and #DF9D00 stays calm, while #00B1DF is the loudest partner.

What is #df2e00 in CMYK for printing?

cmyk(0%, 79%, 100%, 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 #df2e00 warm or cool?

Warm — it scores 10 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DF4700; nudged cooler, #DF0024.

Which Tailwind color is closest to #df2e00?

The red family — its 500 step is #ef4444, ΔE2000 11.3 away. That is a visible difference, so define #df2e00 as a custom token rather than reaching for the built-in.

How do I use #df2e00 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#df2e00] or text-[#df2e00], 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 #df2e00 with 50% opacity?

rgba(223, 46, 0, 0.5), or #df2e0080 in eight-digit hex. Over white that composites to #EF9780; over black, #701700.

Is #df2e00 a web-safe color?

No. The nearest web-safe colour is #CC3300, ΔE2000 3.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #df2e00 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 #df2e00?

The safest is same-hue elevation: linear-gradient(135deg, #FF4C1D, #df2e00 45%, #801A00). For more colour, a short hue run to #C0B800 keeps it rich without turning muddy.
