How to use #ac6c64

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
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Small text on white — under 4.5:1
  • 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 #53312C
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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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.

#ac6c64, answered

What color is #ac6c64?

#ac6c64 is a balanced soft red, closest to Indian Red (ΔE2000 8.1). It sits at 7° on the hue wheel with 30% saturation and 53% lightness, which reads as warm.

What is the RGB value of #ac6c64?

rgb(172, 108, 100) — 172 red, 108 green and 100 blue out of 255, or 67.5% / 42.4% / 39.2% by channel.

What is #ac6c64 in HSL and HSV?

hsl(7, 30%, 53%) and hsv(7, 42%, 67%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ac6c64 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2042 and perceived brightness is 51%, so black text on it reaches 5.08:1.

Should I use black or white text on #ac6c64?

Black. It scores 5.08:1 against #ac6c64, versus 4.13:1 for white — AA at any size.

Is #ac6c64 accessible on a white background?

#ac6c64 on white scores 4.13:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #A7625A to reach 4.5:1, or #7F4B44 for 7:1.

What is the complementary color of #ac6c64?

#64A4AC sits directly opposite on the wheel. Softer options are the split-complements #64AC90 and #6480AC, which give the same contrast with far less vibration.

What colors go well with #ac6c64?

For interface work: #FAF6F5 as the surface, #E3CDCA for borders, #965850 for secondary text, #43897F as an accent and #53312C for hover and pressed states. For a palette, the analogous pair #AC6480 and #AC9064 stays calm, while #64A4AC is the loudest partner.

What is #ac6c64 in CMYK for printing?

cmyk(0%, 37%, 42%, 33%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #ac6c64 warm or cool?

Warm — it scores 18 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AC7D64; nudged cooler, #AE6175.

Which Tailwind color is closest to #ac6c64?

The red family — its 500 step is #ef4444, ΔE2000 14.2 away. That is a visible difference, so define #ac6c64 as a custom token rather than reaching for the built-in.

How do I use #ac6c64 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ac6c64] or text-[#ac6c64], 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 #ac6c64 with 50% opacity?

rgba(172, 108, 100, 0.5), or #ac6c6480 in eight-digit hex. Over white that composites to #D6B6B2; over black, #563632.

Is #ac6c64 a web-safe color?

No. The nearest web-safe colour is #996666, ΔE2000 5.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #ac6c64 mean?
