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

How to use #c9ac39

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #64551B
Safe as a 1px border on white
No — use #AB922F

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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.

#c9ac39, answered

What color is #c9ac39?

#c9ac39 is a balanced vivid yellow, closest to Goldenrod (ΔE2000 6.6). It sits at 48° on the hue wheel with 57% saturation and 51% lightness, which reads as warm.

What is the RGB value of #c9ac39?

rgb(201, 172, 57) — 201 red, 172 green and 57 blue out of 255, or 78.8% / 67.5% / 22.4% by channel.

What is #c9ac39 in HSL and HSV?

hsl(48, 57%, 51%) and hsv(48, 72%, 79%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #c9ac39 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4222 and perceived brightness is 68%, so black text on it reaches 9.44:1.

Should I use black or white text on #c9ac39?

Black. It scores 9.44:1 against #c9ac39, versus 2.22:1 for white — AAA at any size.

Is #c9ac39 accessible on a white background?

#c9ac39 on white scores 2.22:1, which fails WCAG AA at every size. Darken it to #877325 to reach 4.5:1, or #67581C for 7:1.

What is the complementary color of #c9ac39?

#3956C9 sits directly opposite on the wheel. Softer options are the split-complements #399EC9 and #6439C9, which give the same contrast with far less vibration.

What colors go well with #c9ac39?

For interface work: #FAF9F4 as the surface, #EDE4C0 for borders, #9B8B4B for secondary text, #347ACE as an accent and #64551B for hover and pressed states. For a palette, the analogous pair #C96439 and #9EC939 stays calm, while #3956C9 is the loudest partner.

What is #c9ac39 in CMYK for printing?

cmyk(0%, 14%, 72%, 21%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #c9ac39 warm or cool?

Warm — it scores 15 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C98B39; nudged cooler, #B3CB37.

Which Tailwind color is closest to #c9ac39?

The yellow family — its 500 step is #eab308, ΔE2000 7.8 away. That is a visible difference, so define #c9ac39 as a custom token rather than reaching for the built-in.

How do I use #c9ac39 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#c9ac39] or text-[#c9ac39], 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 #c9ac39 with 50% opacity?

rgba(201, 172, 57, 0.5), or #c9ac3980 in eight-digit hex. Over white that composites to #E4D69C; over black, #65561D.

Is #c9ac39 a web-safe color?

No. The nearest web-safe colour is #CC9933, ΔE2000 8.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #c9ac39 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 chroma the effect is amplified — it will dominate whatever sits beside it.
