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

A Tailwind-shaped ramp built around this exact hex. #cabe21 is pinned to step 600; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.

How to use #cabe21

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 #6E6712
Safe as a 1px border on white
No — use #9E951A

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.

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.

#cabe21, answered

What color is #cabe21?

#cabe21 is a balanced vivid yellow, closest to Dark Khaki (ΔE2000 9.6). It sits at 56° on the hue wheel with 72% saturation and 46% lightness, which reads as warm.

What is the RGB value of #cabe21?

rgb(202, 190, 33) — 202 red, 190 green and 33 blue out of 255, or 79.2% / 74.5% / 12.9% by channel.

What is #cabe21 in HSL and HSV?

hsl(56, 72%, 46%) and hsv(56, 84%, 79%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cabe21 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4949 and perceived brightness is 72%, so black text on it reaches 10.90:1.

Should I use black or white text on #cabe21?

Black. It scores 10.90:1 against #cabe21, versus 1.93:1 for white — AAA at any size.

Is #cabe21 accessible on a white background?

#cabe21 on white scores 1.93:1, which fails WCAG AA at every size. Darken it to #807815 to reach 4.5:1, or #5C570F for 7:1.

What is the complementary color of #cabe21?

#212DCA sits directly opposite on the wheel. Softer options are the split-complements #2182CA and #6921CA, which give the same contrast with far less vibration.

What colors go well with #cabe21?

For interface work: #FAFAF4 as the surface, #EDE9C0 for borders, #9B954B for secondary text, #1C56CF as an accent and #6E6712 for hover and pressed states. For a palette, the analogous pair #CA6921 and #82CA21 stays calm, while #212DCA is the loudest partner.

What is #cabe21 in CMYK for printing?

cmyk(0%, 6%, 84%, 21%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #cabe21 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 #CA8D21; nudged cooler, #99CC1F.

Which Tailwind color is closest to #cabe21?

The yellow family — its 500 step is #eab308, ΔE2000 11.4 away. That is a visible difference, so define #cabe21 as a custom token rather than reaching for the built-in.

How do I use #cabe21 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cabe21] or text-[#cabe21], 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 #cabe21 with 50% opacity?

rgba(202, 190, 33, 0.5), or #cabe2180 in eight-digit hex. Over white that composites to #E5DF90; over black, #655F11.

Is #cabe21 a web-safe color?

No. The nearest web-safe colour is #CCCC33, ΔE2000 4.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #cabe21 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 #cabe21?

The safest is same-hue elevation: linear-gradient(135deg, #E1D647, #cabe21 45%, #6E6712). For more colour, a short hue run to #4CB01D keeps it rich without turning muddy.
