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 #cdb739

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 #665B1A
Safe as a 1px border on white
No — use #A5922A

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.

Transparency

What each alpha value actually composites to. The top row is #cdb739 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.

#cdb739, answered

What color is #cdb739?

#cdb739 is a balanced vivid yellow, closest to Dark Khaki (ΔE2000 8.2). It sits at 51° on the hue wheel with 60% saturation and 51% lightness, which reads as warm.

What is the RGB value of #cdb739?

rgb(205, 183, 57) — 205 red, 183 green and 57 blue out of 255, or 80.4% / 71.8% / 22.4% by channel.

What is #cdb739 in HSL and HSV?

hsl(51, 60%, 51%) and hsv(51, 72%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cdb739 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4714 and perceived brightness is 71%, so black text on it reaches 10.43:1.

Should I use black or white text on #cdb739?

Black. It scores 10.43:1 against #cdb739, versus 2.01:1 for white — AAA at any size.

Is #cdb739 accessible on a white background?

#cdb739 on white scores 2.01:1, which fails WCAG AA at every size. Darken it to #847521 to reach 4.5:1, or #635819 for 7:1.

What is the complementary color of #cdb739?

#394FCD sits directly opposite on the wheel. Softer options are the split-complements #3999CD and #6D39CD, which give the same contrast with far less vibration.

What colors go well with #cdb739?

For interface work: #FAFAF4 as the surface, #EDE6C0 for borders, #9B8F4B for secondary text, #3473D2 as an accent and #665B1A for hover and pressed states. For a palette, the analogous pair #CD6D39 and #99CD39 stays calm, while #394FCD is the loudest partner.

What is #cdb739 in CMYK for printing?

cmyk(0%, 11%, 72%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #cdb739 warm or cool?

Warm — it scores 18 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CD9139; nudged cooler, #AED037.

Which Tailwind color is closest to #cdb739?

The yellow family — its 500 step is #eab308, ΔE2000 8.8 away. That is a visible difference, so define #cdb739 as a custom token rather than reaching for the built-in.

How do I use #cdb739 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cdb739] or text-[#cdb739], 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 #cdb739 with 50% opacity?

rgba(205, 183, 57, 0.5), or #cdb73980 in eight-digit hex. Over white that composites to #E6DB9C; over black, #675C1D.

Is #cdb739 a web-safe color?

No. The nearest web-safe colour is #CCCC33, ΔE2000 7.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #cdb739 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.

What gradient works with #cdb739?

The safest is same-hue elevation: linear-gradient(135deg, #D9C96A, #cdb739 45%, #665B1A). For more colour, a short hue run to #66B92F keeps it rich without turning muddy.
