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 #acab79

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 #4F4E31
Safe as a 1px border on white
No — use #99985F

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.

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.

#acab79, answered

What color is #acab79?

#acab79 is a balanced soft yellow, closest to Dark Khaki (ΔE2000 6.4). It sits at 59° on the hue wheel with 24% saturation and 58% lightness, which reads as warm.

What is the RGB value of #acab79?

rgb(172, 171, 121) — 172 red, 171 green and 121 blue out of 255, or 67.5% / 67.1% / 47.5% by channel.

What is #acab79 in HSL and HSV?

hsl(59, 24%, 58%) and hsv(59, 30%, 67%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #acab79 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3928 and perceived brightness is 65%, so black text on it reaches 8.86:1.

Should I use black or white text on #acab79?

Black. It scores 8.86:1 against #acab79, versus 2.37:1 for white — AAA at any size.

Is #acab79 accessible on a white background?

#acab79 on white scores 2.37:1, which fails WCAG AA at every size. Darken it to #79784B to reach 4.5:1, or #5A5938 for 7:1.

What is the complementary color of #acab79?

#797AAC sits directly opposite on the wheel. Softer options are the split-complements #7994AC and #9279AC, which give the same contrast with far less vibration.

What colors go well with #acab79?

For interface work: #F9F9F6 as the surface, #E0DFCD for borders, #8E8D58 for secondary text, #7585B0 as an accent and #4F4E31 for hover and pressed states. For a palette, the analogous pair #AC9279 and #94AC79 stays calm, while #797AAC is the loudest partner.

What is #acab79 in CMYK for printing?

cmyk(0%, 1%, 30%, 33%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #acab79 warm or cool?

Warm — it scores 33 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AC9879; nudged cooler, #9BAE77.

Which Tailwind color is closest to #acab79?

The lime family — its 500 step is #84cc16, ΔE2000 18.8 away. That is a visible difference, so define #acab79 as a custom token rather than reaching for the built-in.

How do I use #acab79 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#acab79] or text-[#acab79], 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 #acab79 with 50% opacity?

rgba(172, 171, 121, 0.5), or #acab7980 in eight-digit hex. Over white that composites to #D6D5BC; over black, #56563D.

Is #acab79 a web-safe color?

No. The nearest web-safe colour is #999966, ΔE2000 5.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #acab79 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 #acab79?

The safest is same-hue elevation: linear-gradient(135deg, #C4C39F, #acab79 45%, #4F4E31). For more colour, a short hue run to #76A066 keeps it rich without turning muddy.
