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

A Tailwind-shaped ramp built around this exact hex. #acac5f is pinned to step 500; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.

How to use #acac5f

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 #54542C
Safe as a 1px border on white
No — use #98984F

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 #acac5f 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.

#acac5f, answered

What color is #acac5f?

#acac5f is a balanced soft yellow, closest to Dark Khaki (ΔE2000 3.8). It sits at 60° on the hue wheel with 32% saturation and 52% lightness, which reads as warm.

What is the RGB value of #acac5f?

rgb(172, 172, 95) — 172 red, 172 green and 95 blue out of 255, or 67.5% / 67.5% / 37.3% by channel.

What is #acac5f in HSL and HSV?

hsl(60, 32%, 52%) and hsv(60, 45%, 67%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #acac5f a light or a dark color?

It is a mid-tone. Relative luminance is 0.3910 and perceived brightness is 65%, so black text on it reaches 8.82:1.

Should I use black or white text on #acac5f?

Black. It scores 8.82:1 against #acac5f, versus 2.38:1 for white — AAA at any size.

Is #acac5f accessible on a white background?

#acac5f on white scores 2.38:1, which fails WCAG AA at every size. Darken it to #77773E to reach 4.5:1, or #59592E for 7:1.

What is the complementary color of #acac5f?

#5F5FAC sits directly opposite on the wheel. Softer options are the split-complements #5F86AC and #865FAC, which give the same contrast with far less vibration.

What colors go well with #acac5f?

For interface work: #FAFAF5 as the surface, #E3E3C9 for borders, #97974E for secondary text, #5A70B1 as an accent and #54542C for hover and pressed states. For a palette, the analogous pair #AC865F and #86AC5F stays calm, while #5F5FAC is the loudest partner.

What is #acac5f in CMYK for printing?

cmyk(0%, 0%, 45%, 33%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #acac5f warm or cool?

Warm — it scores 27 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AC905F; nudged cooler, #91AF5D.

Which Tailwind color is closest to #acac5f?

The lime family — its 500 step is #84cc16, ΔE2000 15.5 away. That is a visible difference, so define #acac5f as a custom token rather than reaching for the built-in.

How do I use #acac5f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#acac5f] or text-[#acac5f], 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 #acac5f with 50% opacity?

rgba(172, 172, 95, 0.5), or #acac5f80 in eight-digit hex. Over white that composites to #D6D6AF; over black, #565630.

Is #acac5f a web-safe color?

No. The nearest web-safe colour is #999966, ΔE2000 7.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #acac5f mean?

As a yellow, it reads optimistic, alert, cheap-and-cheerful. The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail. At this moderate chroma the association is present but not shouted.

What gradient works with #acac5f?

The safest is same-hue elevation: linear-gradient(135deg, #C1C187, #acac5f 45%, #54542C). For more colour, a short hue run to #649C51 keeps it rich without turning muddy.
