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.

How to use #cefe2c

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 #627F01
Safe as a 1px border on white
No — use #7B9F01

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.

What each alpha value actually composites to. The top row is #cefe2c 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.

#cefe2c, answered

What color is #cefe2c?

#cefe2c is a balanced electric green, closest to Green Yellow (ΔE2000 5). It sits at 74° on the hue wheel with 99% saturation and 58% lightness, which reads as warm.

What is the RGB value of #cefe2c?

rgb(206, 254, 44) — 206 red, 254 green and 44 blue out of 255, or 80.8% / 99.6% / 17.3% by channel.

What is #cefe2c in HSL and HSV?

hsl(74, 99%, 58%) and hsv(74, 83%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cefe2c a light or a dark color?

It is a light color. Relative luminance is 0.8419 and perceived brightness is 88%, so black text on it reaches 17.84:1.

Should I use black or white text on #cefe2c?

Black. It scores 17.84:1 against #cefe2c, versus 1.18:1 for white — AAA at any size.

Is #cefe2c accessible on a white background?

#cefe2c on white scores 1.18:1, which fails WCAG AA at every size. Darken it to #607C01 to reach 4.5:1, or #485D00 for 7:1.

What is the complementary color of #cefe2c?

#5C2CFE sits directly opposite on the wheel. Softer options are the split-complements #2C65FE and #C52CFE, which give the same contrast with far less vibration.

What colors go well with #cefe2c?

For interface work: #F9FAF4 as the surface, #E2EDC0 for borders, #899B4B for secondary text, #2B2FFF as an accent and #627F01 for hover and pressed states. For a palette, the analogous pair #FEC52C and #65FE2C stays calm, while #5C2CFE is the loudest partner.

What is #cefe2c in CMYK for printing?

cmyk(19%, 0%, 83%, 0%). 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 #cefe2c warm or cool?

Warm — it scores 36 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #FEE12C; nudged cooler, #81FF2B.

Which Tailwind color is closest to #cefe2c?

The lime family — its 500 step is #84cc16, ΔE2000 13.4 away. That is a visible difference, so define #cefe2c as a custom token rather than reaching for the built-in.

How do I use #cefe2c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cefe2c] or text-[#cefe2c], 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 #cefe2c with 50% opacity?

rgba(206, 254, 44, 0.5), or #cefe2c80 in eight-digit hex. Over white that composites to #E7FF96; over black, #677F16.

Is #cefe2c a web-safe color?

No. The nearest web-safe colour is #CCFF33, ΔE2000 0.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #cefe2c mean?

As a green, it reads safe, growing, natural. Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #cefe2c?

The safest is same-hue elevation: linear-gradient(135deg, #DCFE69, #cefe2c 45%, #627F01). For more colour, a short hue run to #13FE0D keeps it rich without turning muddy.
