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 #ce342f

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • 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

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 #ce342f 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.

#ce342f, answered

What color is #ce342f?

#ce342f is a balanced vivid red, closest to Crimson (ΔE2000 6.1). It sits at 2° on the hue wheel with 63% saturation and 50% lightness, which reads as warm.

What is the RGB value of #ce342f?

rgb(206, 52, 47) — 206 red, 52 green and 47 blue out of 255, or 80.8% / 20.4% / 18.4% by channel.

What is #ce342f in HSL and HSV?

hsl(2, 63%, 50%) and hsv(2, 77%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ce342f a light or a dark color?

It is a dark color. Relative luminance is 0.1578 and perceived brightness is 47%, so white text on it reaches 5.05:1.

Should I use black or white text on #ce342f?

White. It scores 5.05:1 against #ce342f, versus 4.16:1 for black — AA at any size.

Is #ce342f accessible on a white background?

#ce342f on white scores 5.05:1, which clears AA at every size but not AAA.

What is the complementary color of #ce342f?

#2FC9CE sits directly opposite on the wheel. Softer options are the split-complements #2FCE84 and #2F79CE, which give the same contrast with far less vibration.

What colors go well with #ce342f?

For interface work: #FAF4F4 as the surface, #EDC1C0 for borders, #9B4D4B for secondary text, #22AA8C as an accent and #681A18 for hover and pressed states. For a palette, the analogous pair #CE2F79 and #CE842F stays calm, while #2FC9CE is the loudest partner.

What is #ce342f in CMYK for printing?

cmyk(0%, 75%, 77%, 19%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #ce342f warm or cool?

Warm — it scores 16 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CE592F; nudged cooler, #D02D63.

Which Tailwind color is closest to #ce342f?

The red family — its 500 step is #ef4444, ΔE2000 8.6 away. That is a visible difference, so define #ce342f as a custom token rather than reaching for the built-in.

How do I use #ce342f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ce342f] or text-[#ce342f], 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 #ce342f with 50% opacity?

rgba(206, 52, 47, 0.5), or #ce342f80 in eight-digit hex. Over white that composites to #E79A97; over black, #671A18.

Is #ce342f a web-safe color?

No. The nearest web-safe colour is #CC3333, ΔE2000 1.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #ce342f 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 #ce342f?

The safest is same-hue elevation: linear-gradient(135deg, #DB6360, #ce342f 45%, #681A18). For more colour, a short hue run to #B59729 keeps it rich without turning muddy.
