Colour vision deficiency

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.

Color scale — 50 to 950

How to use #cd3c1e

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.

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.

#cd3c1e, answered

What color is #cd3c1e?

#cd3c1e is a balanced vivid red, closest to Red (ΔE2000 8.5). It sits at 10° on the hue wheel with 75% saturation and 46% lightness, which reads as warm.

What is the RGB value of #cd3c1e?

rgb(205, 60, 30) — 205 red, 60 green and 30 blue out of 255, or 80.4% / 23.5% / 11.8% by channel.

What is #cd3c1e in HSL and HSV?

hsl(10, 75%, 46%) and hsv(10, 85%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cd3c1e a light or a dark color?

It is a dark color. Relative luminance is 0.1630 and perceived brightness is 48%, so white text on it reaches 4.93:1.

Should I use black or white text on #cd3c1e?

White. It scores 4.93:1 against #cd3c1e, versus 4.26:1 for black — AA at any size.

Is #cd3c1e accessible on a white background?

#cd3c1e on white scores 4.93:1, which clears AA at every size but not AAA.

What is the complementary color of #cd3c1e?

#1EAFCD sits directly opposite on the wheel. Softer options are the split-complements #1ECD94 and #1E57CD, which give the same contrast with far less vibration.

What colors go well with #cd3c1e?

For interface work: #FAF5F4 as the surface, #EDC7C0 for borders, #9B584B for secondary text, #16B6A9 as an accent and #6F2110 for hover and pressed states. For a palette, the analogous pair #CD1E57 and #CD941E stays calm, while #1EAFCD is the loudest partner.

What is #cd3c1e in CMYK for printing?

cmyk(0%, 71%, 85%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #cd3c1e warm or cool?

Warm — it scores 11 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CD551E; nudged cooler, #CF1C3F.

Which Tailwind color is closest to #cd3c1e?

The red family — its 500 step is #ef4444, ΔE2000 10.6 away. That is a visible difference, so define #cd3c1e as a custom token rather than reaching for the built-in.

How do I use #cd3c1e in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cd3c1e] or text-[#cd3c1e], 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 #cd3c1e with 50% opacity?

rgba(205, 60, 30, 0.5), or #cd3c1e80 in eight-digit hex. Over white that composites to #E69E8F; over black, #671E0F.

Is #cd3c1e a web-safe color?

No. The nearest web-safe colour is #CC3333, ΔE2000 6.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #cd3c1e 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 #cd3c1e?
