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 #cbab21

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 #6E5C12
Safe as a 1px border on white
No — use #AC911C

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 #cbab21 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.

#cbab21, answered

What color is #cbab21?

#cbab21 is a balanced vivid yellow, closest to Goldenrod (ΔE2000 6). It sits at 49° on the hue wheel with 72% saturation and 46% lightness, which reads as warm.

What is the RGB value of #cbab21?

rgb(203, 171, 33) — 203 red, 171 green and 33 blue out of 255, or 79.6% / 67.1% / 12.9% by channel.

What is #cbab21 in HSL and HSV?

hsl(49, 72%, 46%) and hsv(49, 84%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cbab21 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4193 and perceived brightness is 67%, so black text on it reaches 9.39:1.

Should I use black or white text on #cbab21?

Black. It scores 9.39:1 against #cbab21, versus 2.24:1 for white — AAA at any size.

Is #cbab21 accessible on a white background?

#cbab21 on white scores 2.24:1, which fails WCAG AA at every size. Darken it to #897416 to reach 4.5:1, or #665611 for 7:1.

What is the complementary color of #cbab21?

#2141CB sits directly opposite on the wheel. Softer options are the split-complements #2196CB and #5621CB, which give the same contrast with far less vibration.

What colors go well with #cbab21?

For interface work: #FAF9F4 as the surface, #EDE4C0 for borders, #9B8C4B for secondary text, #1C6BD0 as an accent and #6E5C12 for hover and pressed states. For a palette, the analogous pair #CB5621 and #96CB21 stays calm, while #2141CB is the loudest partner.

What is #cbab21 in CMYK for printing?

cmyk(0%, 16%, 84%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #cbab21 warm or cool?

Warm — it scores 16 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CB8521; nudged cooler, #AECD1F.

Which Tailwind color is closest to #cbab21?

The yellow family — its 500 step is #eab308, ΔE2000 6.8 away. That is a visible difference, so define #cbab21 as a custom token rather than reaching for the built-in.

How do I use #cbab21 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cbab21] or text-[#cbab21], 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 #cbab21 with 50% opacity?

rgba(203, 171, 33, 0.5), or #cbab2180 in eight-digit hex. Over white that composites to #E5D590; over black, #665611.

Is #cbab21 a web-safe color?

No. The nearest web-safe colour is #CC9933, ΔE2000 8.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #cbab21 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 #cbab21?

The safest is same-hue elevation: linear-gradient(135deg, #E1C448, #cbab21 45%, #6E5C12). For more colour, a short hue run to #5EB11D keeps it rich without turning muddy.
