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 #ac9d63

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • 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
  • Text of any size on white — fails WCAG AA
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #534B2C
Safe as a 1px border on white
No — use #A39457

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.

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

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

Transparency

What each alpha value actually composites to. The top row is #ac9d63 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.

#ac9d63, answered

What color is #ac9d63?

#ac9d63 is a balanced soft yellow, closest to Dark Khaki (ΔE2000 8.1). It sits at 48° on the hue wheel with 31% saturation and 53% lightness, which reads as warm.

What is the RGB value of #ac9d63?

rgb(172, 157, 99) — 172 red, 157 green and 99 blue out of 255, or 67.5% / 61.6% / 38.8% by channel.

What is #ac9d63 in HSL and HSV?

hsl(48, 31%, 53%) and hsv(48, 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 #ac9d63 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3379 and perceived brightness is 61%, so black text on it reaches 7.76:1.

Should I use black or white text on #ac9d63?

Black. It scores 7.76:1 against #ac9d63, versus 2.71:1 for white — AAA at any size.

Is #ac9d63 accessible on a white background?

#ac9d63 on white scores 2.71:1, which fails WCAG AA at every size. Darken it to #827645 to reach 4.5:1, or #615834 for 7:1.

What is the complementary color of #ac9d63?

#6372AC sits directly opposite on the wheel. Softer options are the split-complements #6396AC and #7863AC, which give the same contrast with far less vibration.

What colors go well with #ac9d63?

For interface work: #FAF9F5 as the surface, #E3DECA for borders, #968750 for secondary text, #5E84B1 as an accent and #534B2C for hover and pressed states. For a palette, the analogous pair #AC7863 and #96AC63 stays calm, while #6372AC is the loudest partner.

What is #ac9d63 in CMYK for printing?

cmyk(0%, 9%, 42%, 33%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #ac9d63 warm or cool?

Warm — it scores 19 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AC8863; nudged cooler, #A2AE61.

Which Tailwind color is closest to #ac9d63?

The yellow family — its 500 step is #eab308, ΔE2000 16.8 away. That is a visible difference, so define #ac9d63 as a custom token rather than reaching for the built-in.

How do I use #ac9d63 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ac9d63] or text-[#ac9d63], 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 #ac9d63 with 50% opacity?

rgba(172, 157, 99, 0.5), or #ac9d6380 in eight-digit hex. Over white that composites to #D6CEB1; over black, #564F32.

Is #ac9d63 a web-safe color?

No. The nearest web-safe colour is #999966, ΔE2000 5.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #ac9d63 mean?
