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 #c2cd01

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
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • 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 #787F01
Safe as a 1px border on white
No — use #929A01

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The low lightness adds weight and formality.

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 #c2cd01 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.

#c2cd01, answered

What color is #c2cd01?

#c2cd01 is a dark electric yellow, closest to Yellow Green (ΔE2000 9.1). It sits at 63° on the hue wheel with 99% saturation and 40% lightness, which reads as warm.

What is the RGB value of #c2cd01?

rgb(194, 205, 1) — 194 red, 205 green and 1 blue out of 255, or 76.1% / 80.4% / 0.4% by channel.

What is #c2cd01 in HSL and HSV?

hsl(63, 99%, 40%) and hsv(63, 100%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #c2cd01 a light or a dark color?

It is a light color. Relative luminance is 0.5513 and perceived brightness is 74%, so black text on it reaches 12.03:1.

Should I use black or white text on #c2cd01?

Black. It scores 12.03:1 against #c2cd01, versus 1.75:1 for white — AAA at any size.

Is #c2cd01 accessible on a white background?

#c2cd01 on white scores 1.75:1, which fails WCAG AA at every size. Darken it to #757C01 to reach 4.5:1, or #585D00 for 7:1.

What is the complementary color of #c2cd01?

#0C01CD sits directly opposite on the wheel. Softer options are the split-complements #015CCD and #7201CD, which give the same contrast with far less vibration.

What colors go well with #c2cd01?

For interface work: #FAFAF4 as the surface, #EAEDC0 for borders, #979B4B for secondary text, #0029CE as an accent and #787F01 for hover and pressed states. For a palette, the analogous pair #CD7201 and #5CCD01 stays calm, while #0C01CD is the loudest partner.

What is #c2cd01 in CMYK for printing?

cmyk(5%, 0%, 100%, 20%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #c2cd01 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 #CD9201; nudged cooler, #78CE00.

Which Tailwind color is closest to #c2cd01?

The lime family — its 500 step is #84cc16, ΔE2000 11.5 away. That is a visible difference, so define #c2cd01 as a custom token rather than reaching for the built-in.

How do I use #c2cd01 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#c2cd01] or text-[#c2cd01], 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 #c2cd01 with 50% opacity?

rgba(194, 205, 1, 0.5), or #c2cd0180 in eight-digit hex. Over white that composites to #E1E680; over black, #616701.

Is #c2cd01 a web-safe color?

No. The nearest web-safe colour is #CCCC00, ΔE2000 2.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #c2cd01 mean?
