How to use #cf6347

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 #652A1A
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.

#cf6347, answered

What color is #cf6347?

#cf6347 is a balanced vivid red, closest to Tomato (ΔE2000 8.7). It sits at 12° on the hue wheel with 59% saturation and 55% lightness, which reads as warm.

What is the RGB value of #cf6347?

rgb(207, 99, 71) — 207 red, 99 green and 71 blue out of 255, or 81.2% / 38.8% / 27.8% by channel.

What is #cf6347 in HSL and HSV?

hsl(12, 59%, 55%) and hsv(12, 66%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cf6347 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2264 and perceived brightness is 54%, so black text on it reaches 5.53:1.

Should I use black or white text on #cf6347?

Black. It scores 5.53:1 against #cf6347, versus 3.80:1 for white — AA at any size.

Is #cf6347 accessible on a white background?

#cf6347 on white scores 3.80:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #C45133 to reach 4.5:1, or #943D27 for 7:1.

What is the complementary color of #cf6347?

#47B3CF sits directly opposite on the wheel. Softer options are the split-complements #47CFA7 and #476FCF, which give the same contrast with far less vibration.

What colors go well with #cf6347?

For interface work: #FAF6F4 as the surface, #EDC9C0 for borders, #9B5B4B for secondary text, #26A6A0 as an accent and #652A1A for hover and pressed states. For a palette, the analogous pair #CF476F and #CFA747 stays calm, while #47B3CF is the loudest partner.

What is #cf6347 in CMYK for printing?

cmyk(0%, 52%, 66%, 19%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #cf6347 warm or cool?

Warm — it scores 10 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CF7647; nudged cooler, #D1455B.

Which Tailwind color is closest to #cf6347?

The red family — its 500 step is #ef4444, ΔE2000 8.6 away. That is a visible difference, so define #cf6347 as a custom token rather than reaching for the built-in.

How do I use #cf6347 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cf6347] or text-[#cf6347], 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 #cf6347 with 50% opacity?

rgba(207, 99, 71, 0.5), or #cf634780 in eight-digit hex. Over white that composites to #E7B1A3; over black, #683224.

Is #cf6347 a web-safe color?

No. The nearest web-safe colour is #CC6633, ΔE2000 6.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #cf6347 mean?
