How to use #8f3421

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
  • Text on black or near-black surfaces
  • 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

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 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.

Transparency

What each alpha value actually composites to. The top row is #8f3421 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.

#8f3421, answered

What color is #8f3421?

#8f3421 is a dark vivid red, closest to Brown (ΔE2000 6.1). It sits at 10° on the hue wheel with 63% saturation and 35% lightness, which reads as warm.

What is the RGB value of #8f3421?

rgb(143, 52, 33) — 143 red, 52 green and 33 blue out of 255, or 56.1% / 20.4% / 12.9% by channel.

What is #8f3421 in HSL and HSV?

hsl(10, 63%, 35%) and hsv(10, 77%, 56%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8f3421 a light or a dark color?

It is a dark color. Relative luminance is 0.0841 and perceived brightness is 35%, so white text on it reaches 7.83:1.

Should I use black or white text on #8f3421?

White. It scores 7.83:1 against #8f3421, versus 2.68:1 for black — AAA at any size.

Is #8f3421 accessible on a white background?

#8f3421 on white scores 7.83:1, which clears AAA at every size.

What is the complementary color of #8f3421?

#217C8F sits directly opposite on the wheel. Softer options are the split-complements #218F6B and #21458F, which give the same contrast with far less vibration.

What colors go well with #8f3421?

For interface work: #FAF5F4 as the surface, #EDC8C0 for borders, #9B594B for secondary text, #1D928A as an accent and #682618 for hover and pressed states. For a palette, the analogous pair #8F2145 and #8F6B21 stays calm, while #217C8F is the loudest partner.

What is #8f3421 in CMYK for printing?

cmyk(0%, 64%, 77%, 44%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #8f3421 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 #8F4721; nudged cooler, #911F35.

Which Tailwind color is closest to #8f3421?

The red family — its 500 step is #ef4444, ΔE2000 21.1 away. That is a visible difference, so define #8f3421 as a custom token rather than reaching for the built-in.

How do I use #8f3421 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8f3421] or text-[#8f3421], 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 #8f3421 with 50% opacity?

rgba(143, 52, 33, 0.5), or #8f342180 in eight-digit hex. Over white that composites to #C79A90; over black, #481A11.

Is #8f3421 a web-safe color?

No. The nearest web-safe colour is #993333, ΔE2000 6.3 away. The palette only matters for legacy displays and some email clients now.
