How to use #df3f44

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

Works well for
  • Headings from 24px up on white
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Small text on white — under 4.5:1
  • Full-page backgrounds — tiring over long sessions
  • 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
24px / 18.66px bold
Safe as a fill behind white type
No — use #6D1215
Safe as a 1px border on white
Yes

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The mid lightness keeps it versatile in both themes.

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.

Transparency

What each alpha value actually composites to. The top row is #df3f44 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.

#df3f44, answered

What color is #df3f44?

#df3f44 is a balanced vivid red, closest to Crimson (ΔE2000 5.4). It sits at 358° on the hue wheel with 71% saturation and 56% lightness, which reads as warm.

What is the RGB value of #df3f44?

rgb(223, 63, 68) — 223 red, 63 green and 68 blue out of 255, or 87.5% / 24.7% / 26.7% by channel.

What is #df3f44 in HSL and HSV?

hsl(358, 71%, 56%) and hsv(358, 72%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #df3f44 a light or a dark color?

It is a mid-tone. Relative luminance is 0.1966 and perceived brightness is 52%, so black text on it reaches 4.93:1.

Should I use black or white text on #df3f44?

Black. It scores 4.93:1 against #df3f44, versus 4.26:1 for white — AA at any size.

Is #df3f44 accessible on a white background?

#df3f44 on white scores 4.26:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #DD3237 to reach 4.5:1, or #AB1D21 for 7:1.

What is the complementary color of #df3f44?

#3FDFDA sits directly opposite on the wheel. Softer options are the split-complements #3FDF8A and #3F94DF, which give the same contrast with far less vibration.

What colors go well with #df3f44?

For interface work: #FAF4F4 as the surface, #EDC0C1 for borders, #9B4B4D for secondary text, #19B388 as an accent and #6D1215 for hover and pressed states. For a palette, the analogous pair #DF3F94 and #DF8A3F stays calm, while #3FDFDA is the loudest partner.

What is #df3f44 in CMYK for printing?

cmyk(0%, 72%, 70%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #df3f44 warm or cool?

Warm — it scores 18 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DF663F; nudged cooler, #E13D7E.

Which Tailwind color is closest to #df3f44?

The red family — its 500 step is #ef4444, ΔE2000 3.9 away. That is a visible difference, so define #df3f44 as a custom token rather than reaching for the built-in.

How do I use #df3f44 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#df3f44] or text-[#df3f44], 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 #df3f44 with 50% opacity?

rgba(223, 63, 68, 0.5), or #df3f4480 in eight-digit hex. Over white that composites to #EF9FA2; over black, #702022.

Is #df3f44 a web-safe color?

No. The nearest web-safe colour is #CC3333, ΔE2000 5.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #df3f44 mean?
