How to use #df3247

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 #6E111D
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 #df3247 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.

#df3247, answered

What color is #df3247?

#df3247 is a balanced vivid red, closest to Crimson (ΔE2000 3.2). It sits at 353° on the hue wheel with 73% saturation and 54% lightness, which reads as warm.

What is the RGB value of #df3247?

rgb(223, 50, 71) — 223 red, 50 green and 71 blue out of 255, or 87.5% / 19.6% / 27.8% by channel.

What is #df3247 in HSL and HSV?

hsl(353, 73%, 54%) and hsv(353, 78%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #df3247 a light or a dark color?

It is a mid-tone. Relative luminance is 0.1842 and perceived brightness is 51%, so black text on it reaches 4.68:1.

Should I use black or white text on #df3247?

Black. It scores 4.68:1 against #df3247, versus 4.48:1 for white — AA at any size.

Is #df3247 accessible on a white background?

#df3247 on white scores 4.48:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #DE2D43 to reach 4.5:1, or #AE1B2D for 7:1.

What is the complementary color of #df3247?

#32DFCA sits directly opposite on the wheel. Softer options are the split-complements #32DF73 and #329DDF, which give the same contrast with far less vibration.

What colors go well with #df3247?

For interface work: #FAF4F5 as the surface, #EDC0C5 for borders, #9B4B54 for secondary text, #17B57A as an accent and #6E111D for hover and pressed states. For a palette, the analogous pair #DF329D and #DF7332 stays calm, while #32DFCA is the loudest partner.

What is #df3247 in CMYK for printing?

cmyk(0%, 78%, 68%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #df3247 warm or cool?

Warm — it scores 21 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DF5532; nudged cooler, #E12F86.

Which Tailwind color is closest to #df3247?

The rose family — its 500 step is #f43f5e, ΔE2000 6.4 away. That is a visible difference, so define #df3247 as a custom token rather than reaching for the built-in.

How do I use #df3247 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#df3247] or text-[#df3247], 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 #df3247 with 50% opacity?

rgba(223, 50, 71, 0.5), or #df324780 in eight-digit hex. Over white that composites to #EF99A3; over black, #701924.

Is #df3247 a web-safe color?

No. The nearest web-safe colour is #CC3333, ΔE2000 6 away. The palette only matters for legacy displays and some email clients now.
