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 #c4cc2c

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 #656917
Safe as a 1px border on white
No — use #949A21

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.

#c4cc2c, answered

What color is #c4cc2c?

#c4cc2c is a balanced vivid yellow, closest to Yellow Green (ΔE2000 8.8). It sits at 63° on the hue wheel with 65% saturation and 49% lightness, which reads as warm.

What is the RGB value of #c4cc2c?

rgb(196, 204, 44) — 196 red, 204 green and 44 blue out of 255, or 76.9% / 80% / 17.3% by channel.

What is #c4cc2c in HSL and HSV?

hsl(63, 65%, 49%) and hsv(63, 78%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #c4cc2c a light or a dark color?

It is a light color. Relative luminance is 0.5510 and perceived brightness is 75%, so black text on it reaches 12.02:1.

Should I use black or white text on #c4cc2c?

Black. It scores 12.02:1 against #c4cc2c, versus 1.75:1 for white — AAA at any size.

Is #c4cc2c accessible on a white background?

#c4cc2c on white scores 1.75:1, which fails WCAG AA at every size. Darken it to #73781A to reach 4.5:1, or #575B14 for 7:1.

What is the complementary color of #c4cc2c?

#342CCC sits directly opposite on the wheel. Softer options are the split-complements #2C74CC and #842CCC, which give the same contrast with far less vibration.

What colors go well with #c4cc2c?

For interface work: #FAFAF4 as the surface, #EAEDC0 for borders, #979B4B for secondary text, #2749D1 as an accent and #656917 for hover and pressed states. For a palette, the analogous pair #CC842C and #74CC2C stays calm, while #342CCC is the loudest partner.

What is #c4cc2c in CMYK for printing?

cmyk(4%, 0%, 78%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #c4cc2c warm or cool?

Warm — it scores 28 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CC992C; nudged cooler, #8ACE2A.

Which Tailwind color is closest to #c4cc2c?

The lime family — its 500 step is #84cc16, ΔE2000 11.5 away. That is a visible difference, so define #c4cc2c as a custom token rather than reaching for the built-in.

How do I use #c4cc2c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#c4cc2c] or text-[#c4cc2c], 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 #c4cc2c with 50% opacity?

rgba(196, 204, 44, 0.5), or #c4cc2c80 in eight-digit hex. Over white that composites to #E2E696; over black, #626616.

Is #c4cc2c a web-safe color?

No. The nearest web-safe colour is #CCCC33, ΔE2000 1.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #c4cc2c 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.
