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.

How to use #acaf82

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 #4C4E32
Safe as a 1px border on white
No — use #949861

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 #acaf82 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.

#acaf82, answered

What color is #acaf82?

#acaf82 is a balanced soft yellow, closest to Dark Khaki (ΔE2000 7.6). It sits at 64° on the hue wheel with 22% saturation and 60% lightness, which reads as warm.

What is the RGB value of #acaf82?

rgb(172, 175, 130) — 172 red, 175 green and 130 blue out of 255, or 67.5% / 68.6% / 51% by channel.

What is #acaf82 in HSL and HSV?

hsl(64, 22%, 60%) and hsv(64, 26%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #acaf82 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4104 and perceived brightness is 66%, so black text on it reaches 9.21:1.

Should I use black or white text on #acaf82?

Black. It scores 9.21:1 against #acaf82, versus 2.28:1 for white — AAA at any size.

Is #acaf82 accessible on a white background?

#acaf82 on white scores 2.28:1, which fails WCAG AA at every size. Darken it to #76794D to reach 4.5:1, or #575A39 for 7:1.

What is the complementary color of #acaf82?

#8582AF sits directly opposite on the wheel. Softer options are the split-complements #8295AF and #9B82AF, which give the same contrast with far less vibration.

What colors go well with #acaf82?

For interface work: #F9F9F6 as the surface, #DEDFCD for borders, #898C5A for secondary text, #7E88B3 as an accent and #4C4E32 for hover and pressed states. For a palette, the analogous pair #AF9B82 and #95AF82 stays calm, while #8582AF is the loudest partner.

What is #acaf82 in CMYK for printing?

cmyk(2%, 0%, 26%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #acaf82 warm or cool?

Warm — it scores 36 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AFA282; nudged cooler, #9CB180.

Which Tailwind color is closest to #acaf82?

The lime family — its 500 step is #84cc16, ΔE2000 18.8 away. That is a visible difference, so define #acaf82 as a custom token rather than reaching for the built-in.

How do I use #acaf82 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#acaf82] or text-[#acaf82], 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 #acaf82 with 50% opacity?

rgba(172, 175, 130, 0.5), or #acaf8280 in eight-digit hex. Over white that composites to #D6D7C1; over black, #565841.

Is #acaf82 a web-safe color?

No. The nearest web-safe colour is #999999, ΔE2000 17.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #acaf82 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 #acaf82?
