Color scale — 50 to 950

How to use #ac861c

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
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Small text on white — under 4.5:1
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • Thin strokes and 1px borders — they disappear on light UI
  • 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 #6E5512
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.

optimisticalertcheap-and-cheerfulvisible

The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail.

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

Almost never passes contrast against white. Treat it as a surface or a marker, not as text.

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.

#ac861c, answered

What color is #ac861c?

#ac861c is a dark vivid yellow, closest to Dark Goldenrod (ΔE2000 3.5). It sits at 44° on the hue wheel with 72% saturation and 39% lightness, which reads as warm.

What is the RGB value of #ac861c?

rgb(172, 134, 28) — 172 red, 134 green and 28 blue out of 255, or 67.5% / 52.5% / 11% by channel.

What is #ac861c in HSL and HSV?

hsl(44, 72%, 39%) and hsv(44, 84%, 67%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ac861c a light or a dark color?

It is a mid-tone. Relative luminance is 0.2590 and perceived brightness is 55%, so black text on it reaches 6.18:1.

Should I use black or white text on #ac861c?

Black. It scores 6.18:1 against #ac861c, versus 3.40:1 for white — AA at any size.

Is #ac861c accessible on a white background?

#ac861c on white scores 3.40:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #927218 to reach 4.5:1, or #6A5311 for 7:1.

What is the complementary color of #ac861c?

#1C42AC sits directly opposite on the wheel. Softer options are the split-complements #1C8AAC and #3E1CAC, which give the same contrast with far less vibration.

What colors go well with #ac861c?

For interface work: #FAF9F4 as the surface, #EDE1C0 for borders, #9B864B for secondary text, #1866B0 as an accent and #6E5512 for hover and pressed states. For a palette, the analogous pair #AC3E1C and #8AAC1C stays calm, while #1C42AC is the loudest partner.

What is #ac861c in CMYK for printing?

cmyk(0%, 22%, 84%, 33%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #ac861c warm or cool?

Warm — it scores 12 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AC6A1C; nudged cooler, #9FAE1A.

Which Tailwind color is closest to #ac861c?

The yellow family — its 500 step is #eab308, ΔE2000 15.3 away. That is a visible difference, so define #ac861c as a custom token rather than reaching for the built-in.

How do I use #ac861c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ac861c] or text-[#ac861c], 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 #ac861c with 50% opacity?

rgba(172, 134, 28, 0.5), or #ac861c80 in eight-digit hex. Over white that composites to #D6C38E; over black, #56430E.

Is #ac861c a web-safe color?
