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 #c0fc3d

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
  • Status meaning — pair it with an icon or label, never colour alone
  • 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 #577E02
Safe as a 1px border on white
No — use #71A302

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

safegrowingnaturalpermissive

Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.

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

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

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.

#c0fc3d, answered

What color is #c0fc3d?

#c0fc3d is a balanced electric green, closest to Green Yellow (ΔE2000 2.7). It sits at 79° on the hue wheel with 97% saturation and 61% lightness, which reads as warm.

What is the RGB value of #c0fc3d?

rgb(192, 252, 61) — 192 red, 252 green and 61 blue out of 255, or 75.3% / 98.8% / 23.9% by channel.

What is #c0fc3d in HSL and HSV?

hsl(79, 97%, 61%) and hsv(79, 76%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #c0fc3d a light or a dark color?

It is a light color. Relative luminance is 0.8116 and perceived brightness is 87%, so black text on it reaches 17.23:1.

Should I use black or white text on #c0fc3d?

Black. It scores 17.23:1 against #c0fc3d, versus 1.22:1 for white — AAA at any size.

Is #c0fc3d accessible on a white background?

#c0fc3d on white scores 1.22:1, which fails WCAG AA at every size. Darken it to #588002 to reach 4.5:1, or #436101 for 7:1.

What is the complementary color of #c0fc3d?

#793DFC sits directly opposite on the wheel. Softer options are the split-complements #3D61FC and #D83DFC, which give the same contrast with far less vibration.

What colors go well with #c0fc3d?

For interface work: #F8FAF4 as the surface, #DFEDC0 for borders, #829B4B for secondary text, #473AFF as an accent and #577E02 for hover and pressed states. For a palette, the analogous pair #FCD83D and #61FC3D stays calm, while #793DFC is the loudest partner.

What is #c0fc3d in CMYK for printing?

cmyk(24%, 0%, 76%, 1%). 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 #c0fc3d warm or cool?

Warm — it scores 41 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #FCF23D; nudged cooler, #79FE3B.

Which Tailwind color is closest to #c0fc3d?

The lime family — its 500 step is #84cc16, ΔE2000 11.8 away. That is a visible difference, so define #c0fc3d as a custom token rather than reaching for the built-in.

How do I use #c0fc3d in Tailwind CSS?

Inline it as an arbitrary value with bg-[#c0fc3d] or text-[#c0fc3d], 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 #c0fc3d with 50% opacity?

rgba(192, 252, 61, 0.5), or #c0fc3d80 in eight-digit hex. Over white that composites to #E0FE9E; over black, #607E1F.

Is #c0fc3d a web-safe color?

No. The nearest web-safe colour is #CCFF33, ΔE2000 2.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #c0fc3d mean?
