How to use #df6451

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 #6C2014
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 #df6451 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.

#df6451, answered

What color is #df6451?

#df6451 is a balanced vivid red, closest to Tomato (ΔE2000 6.1). It sits at 8° on the hue wheel with 69% saturation and 60% lightness, which reads as warm.

What is the RGB value of #df6451?

rgb(223, 100, 81) — 223 red, 100 green and 81 blue out of 255, or 87.5% / 39.2% / 31.8% by channel.

What is #df6451 in HSL and HSV?

hsl(8, 69%, 60%) and hsv(8, 64%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #df6451 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2540 and perceived brightness is 57%, so black text on it reaches 6.08:1.

Should I use black or white text on #df6451?

Black. It scores 6.08:1 against #df6451, versus 3.45:1 for white — AA at any size.

Is #df6451 accessible on a white background?

#df6451 on white scores 3.45:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #D63F27 to reach 4.5:1, or #A22F1E for 7:1.

What is the complementary color of #df6451?

#51CCDF sits directly opposite on the wheel. Softer options are the split-complements #51DFAB and #5185DF, which give the same contrast with far less vibration.

What colors go well with #df6451?

For interface work: #FAF5F4 as the surface, #EDC6C0 for borders, #9B554B for secondary text, #1CB09F as an accent and #6C2014 for hover and pressed states. For a palette, the analogous pair #DF5185 and #DFAB51 stays calm, while #51CCDF is the loudest partner.

What is #df6451 in CMYK for printing?

cmyk(0%, 55%, 64%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #df6451 warm or cool?

Warm — it scores 12 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DF7D51; nudged cooler, #E14F71.

Which Tailwind color is closest to #df6451?

The red family — its 500 step is #ef4444, ΔE2000 6 away. That is a visible difference, so define #df6451 as a custom token rather than reaching for the built-in.

How do I use #df6451 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#df6451] or text-[#df6451], 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 #df6451 with 50% opacity?

rgba(223, 100, 81, 0.5), or #df645180 in eight-digit hex. Over white that composites to #EFB2A8; over black, #703229.

Is #df6451 a web-safe color?

No. The nearest web-safe colour is #CC6666, ΔE2000 7.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #df6451 mean?
