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. #c2df1f 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 #c2df1f

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 #617010
Safe as a 1px border on white
No — use #879C16

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 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.

#c2df1f, answered

What color is #c2df1f?

#c2df1f is a balanced electric yellow, closest to Yellow Green (ΔE2000 7.7). It sits at 69° on the hue wheel with 76% saturation and 50% lightness, which reads as warm.

What is the RGB value of #c2df1f?

rgb(194, 223, 31) — 194 red, 223 green and 31 blue out of 255, or 76.1% / 87.5% / 12.2% by channel.

What is #c2df1f in HSL and HSV?

hsl(69, 76%, 50%) and hsv(69, 86%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #c2df1f a light or a dark color?

It is a light color. Relative luminance is 0.6434 and perceived brightness is 79%, so black text on it reaches 13.87:1.

Should I use black or white text on #c2df1f?

Black. It scores 13.87:1 against #c2df1f, versus 1.51:1 for white — AAA at any size.

Is #c2df1f accessible on a white background?

#c2df1f on white scores 1.51:1, which fails WCAG AA at every size. Darken it to #6C7C11 to reach 4.5:1, or #515D0D for 7:1.

What is the complementary color of #c2df1f?

#3C1FDF sits directly opposite on the wheel. Softer options are the split-complements #1F62DF and #9C1FDF, which give the same contrast with far less vibration.

What colors go well with #c2df1f?

For interface work: #F9FAF4 as the surface, #E6EDC0 for borders, #8F9B4B for secondary text, #1A2EE4 as an accent and #617010 for hover and pressed states. For a palette, the analogous pair #DF9C1F and #62DF1F stays calm, while #3C1FDF is the loudest partner.

What is #c2df1f in CMYK for printing?

cmyk(13%, 0%, 86%, 13%). 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 #c2df1f warm or cool?

Warm — it scores 33 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DFB61F; nudged cooler, #7BE21C.

Which Tailwind color is closest to #c2df1f?

The lime family — its 500 step is #84cc16, ΔE2000 9.9 away. That is a visible difference, so define #c2df1f as a custom token rather than reaching for the built-in.

How do I use #c2df1f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#c2df1f] or text-[#c2df1f], 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 #c2df1f with 50% opacity?

rgba(194, 223, 31, 0.5), or #c2df1f80 in eight-digit hex. Over white that composites to #E1EF8F; over black, #617010.

Is #c2df1f a web-safe color?

No. The nearest web-safe colour is #CCCC33, ΔE2000 6.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #c2df1f mean?
