Color scale — 50 to 950

How to use #b3ac64

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 #56522A
Safe as a 1px border on white
No — use #9C954D

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.

#b3ac64, answered

What color is #b3ac64?

#b3ac64 is a balanced soft yellow, closest to Dark Khaki (ΔE2000 3.1). It sits at 55° on the hue wheel with 34% saturation and 55% lightness, which reads as warm.

What is the RGB value of #b3ac64?

rgb(179, 172, 100) — 179 red, 172 green and 100 blue out of 255, or 70.2% / 67.5% / 39.2% by channel.

What is #b3ac64 in HSL and HSV?

hsl(55, 34%, 55%) and hsv(55, 44%, 70%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b3ac64 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4001 and perceived brightness is 66%, so black text on it reaches 9.00:1.

Should I use black or white text on #b3ac64?

Black. It scores 9.00:1 against #b3ac64, versus 2.33:1 for white — AAA at any size.

Is #b3ac64 accessible on a white background?

#b3ac64 on white scores 2.33:1, which fails WCAG AA at every size. Darken it to #7E783E to reach 4.5:1, or #5B572D for 7:1.

What is the complementary color of #b3ac64?

#646BB3 sits directly opposite on the wheel. Softer options are the split-complements #6492B3 and #8564B3, which give the same contrast with far less vibration.

What colors go well with #b3ac64?

For interface work: #FAFAF5 as the surface, #E4E2C8 for borders, #9A934C for secondary text, #5F7DB8 as an accent and #56522A for hover and pressed states. For a palette, the analogous pair #B38564 and #92B364 stays calm, while #646BB3 is the loudest partner.

What is #b3ac64 in CMYK for printing?

cmyk(0%, 4%, 44%, 30%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b3ac64 warm or cool?

Warm — it scores 21 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B38F64; nudged cooler, #9EB562.

Which Tailwind color is closest to #b3ac64?

The yellow family — its 500 step is #eab308, ΔE2000 16 away. That is a visible difference, so define #b3ac64 as a custom token rather than reaching for the built-in.

How do I use #b3ac64 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b3ac64] or text-[#b3ac64], 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 #b3ac64 with 50% opacity?

rgba(179, 172, 100, 0.5), or #b3ac6480 in eight-digit hex. Over white that composites to #D9D6B2; over black, #5A5632.

Is #b3ac64 a web-safe color?

No. The nearest web-safe colour is #CC9966, ΔE2000 16.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #b3ac64 mean?
