How to use #a54c30

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

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 #a54c30 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.

#a54c30, answered

What color is #a54c30?

#a54c30 is a dark vivid red, closest to Sienna (ΔE2000 3.7). It sits at 14° on the hue wheel with 55% saturation and 42% lightness, which reads as warm.

What is the RGB value of #a54c30?

rgb(165, 76, 48) — 165 red, 76 green and 48 blue out of 255, or 64.7% / 29.8% / 18.8% by channel.

What is #a54c30 in HSL and HSV?

hsl(14, 55%, 42%) and hsv(14, 71%, 65%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a54c30 a light or a dark color?

It is a dark color. Relative luminance is 0.1338 and perceived brightness is 43%, so white text on it reaches 5.71:1.

Should I use black or white text on #a54c30?

White. It scores 5.71:1 against #a54c30, versus 3.68:1 for black — AA at any size.

Is #a54c30 accessible on a white background?

#a54c30 on white scores 5.71:1, which clears AA at every size but not AAA.

What is the complementary color of #a54c30?

#3089A5 sits directly opposite on the wheel. Softer options are the split-complements #30A587 and #304FA5, which give the same contrast with far less vibration.

What colors go well with #a54c30?

For interface work: #FAF6F4 as the surface, #EDCBC0 for borders, #9B5E4B for secondary text, #2AA2A1 as an accent and #632E1D for hover and pressed states. For a palette, the analogous pair #A5304F and #A58730 stays calm, while #3089A5 is the loudest partner.

What is #a54c30 in CMYK for printing?

cmyk(0%, 54%, 71%, 35%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a54c30 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 #A55A30; nudged cooler, #A72E3D.

Which Tailwind color is closest to #a54c30?

The red family — its 500 step is #ef4444, ΔE2000 15.9 away. That is a visible difference, so define #a54c30 as a custom token rather than reaching for the built-in.

How do I use #a54c30 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a54c30] or text-[#a54c30], 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 #a54c30 with 50% opacity?

rgba(165, 76, 48, 0.5), or #a54c3080 in eight-digit hex. Over white that composites to #D2A698; over black, #532618.

Is #a54c30 a web-safe color?

No. The nearest web-safe colour is #993333, ΔE2000 10.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #a54c30 mean?
