Large text — 24px regular or 18.66px bold and above — only needs 3:1, so #CF3B0D is enough for headings on white. Non-text elements such as icons, chart strokes and focus rings also sit at 3:1 under WCAG 2.2 (1.4.11).

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 #cf3b0d

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
  • 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.

#cf3b0d, answered

What color is #cf3b0d?

#cf3b0d is a dark electric red, closest to Red (ΔE2000 8.5). It sits at 14° on the hue wheel with 88% saturation and 43% lightness, which reads as warm.

What is the RGB value of #cf3b0d?

rgb(207, 59, 13) — 207 red, 59 green and 13 blue out of 255, or 81.2% / 23.1% / 5.1% by channel.

What is #cf3b0d in HSL and HSV?

hsl(14, 88%, 43%) and hsv(14, 94%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cf3b0d a light or a dark color?

It is a dark color. Relative luminance is 0.1642 and perceived brightness is 48%, so white text on it reaches 4.90:1.

Should I use black or white text on #cf3b0d?

White. It scores 4.90:1 against #cf3b0d, versus 4.28:1 for black — AA at any size.

Is #cf3b0d accessible on a white background?

#cf3b0d on white scores 4.90:1, which clears AA at every size but not AAA.

What is the complementary color of #cf3b0d?

#0DA1CF sits directly opposite on the wheel. Softer options are the split-complements #0DCF9C and #0D40CF, which give the same contrast with far less vibration.

What colors go well with #cf3b0d?

For interface work: #FAF6F4 as the surface, #EDCAC0 for borders, #9B5E4B for secondary text, #08C4C2 as an accent and #782208 for hover and pressed states. For a palette, the analogous pair #CF0D40 and #CF9C0D stays calm, while #0DA1CF is the loudest partner.

What is #cf3b0d in CMYK for printing?

cmyk(0%, 72%, 94%, 19%). 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 #cf3b0d warm or cool?

Warm — it scores 9 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CF4F0D; nudged cooler, #D10B25.

Which Tailwind color is closest to #cf3b0d?

The red family — its 500 step is #ef4444, ΔE2000 12.4 away. That is a visible difference, so define #cf3b0d as a custom token rather than reaching for the built-in.

How do I use #cf3b0d in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cf3b0d] or text-[#cf3b0d], 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 #cf3b0d with 50% opacity?

rgba(207, 59, 13, 0.5), or #cf3b0d80 in eight-digit hex. Over white that composites to #E79D86; over black, #681E07.

Is #cf3b0d a web-safe color?

No. The nearest web-safe colour is #CC3300, ΔE2000 1.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #cf3b0d 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 #cf3b0d?
