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 #aca385

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 #4C4634
Safe as a 1px border on white
No — use #9E9370

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 #aca385 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.

#aca385, answered

What color is #aca385?

#aca385 is a balanced soft yellow, closest to Tan (ΔE2000 9.9). It sits at 46° on the hue wheel with 19% saturation and 60% lightness, which reads as warm.

What is the RGB value of #aca385?

rgb(172, 163, 133) — 172 red, 163 green and 133 blue out of 255, or 67.5% / 63.9% / 52.2% by channel.

What is #aca385 in HSL and HSV?

hsl(46, 19%, 60%) and hsv(46, 23%, 67%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aca385 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3666 and perceived brightness is 64%, so black text on it reaches 8.33:1.

Should I use black or white text on #aca385?

Black. It scores 8.33:1 against #aca385, versus 2.52:1 for white — AAA at any size.

Is #aca385 accessible on a white background?

#aca385 on white scores 2.52:1, which fails WCAG AA at every size. Darken it to #7F7656 to reach 4.5:1, or #5D5740 for 7:1.

What is the complementary color of #aca385?

#858EAC sits directly opposite on the wheel. Softer options are the split-complements #85A1AC and #9085AC, which give the same contrast with far less vibration.

What colors go well with #aca385?

For interface work: #F9F8F6 as the surface, #DEDACE for borders, #897F5D for secondary text, #4F667D as an accent and #4C4634 for hover and pressed states. For a palette, the analogous pair #AC9085 and #A1AC85 stays calm, while #858EAC is the loudest partner.

What is #aca385 in CMYK for printing?

cmyk(0%, 5%, 23%, 33%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #aca385 warm or cool?

Warm — it scores 30 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AC9785; nudged cooler, #A8AE83.

Which Tailwind color is closest to #aca385?

The stone family — its 500 step is #78716c, ΔE2000 20 away. That is a visible difference, so define #aca385 as a custom token rather than reaching for the built-in.

How do I use #aca385 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#aca385] or text-[#aca385], 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 #aca385 with 50% opacity?

rgba(172, 163, 133, 0.5), or #aca38580 in eight-digit hex. Over white that composites to #D6D1C2; over black, #565243.

Is #aca385 a web-safe color?

No. The nearest web-safe colour is #999999, ΔE2000 12.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #aca385 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 #aca385?

The safest is same-hue elevation: linear-gradient(135deg, #C5BEA9, #aca385 45%, #4C4634). For more colour, a short hue run to #88A073 keeps it rich without turning muddy.
