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 #cefc9b

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
  • Card and section backgrounds
  • 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
  • White text placed on it
  • 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 #437C04
Safe as a 1px border on white
No — use #5AA705

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 lightness keeps it airy and approachable.

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.

#cefc9b, answered

What color is #cefc9b?

#cefc9b is a light electric green, closest to Pale Green (ΔE2000 7.8). It sits at 89° on the hue wheel with 94% saturation and 80% lightness, which reads as neutral.

What is the RGB value of #cefc9b?

rgb(206, 252, 155) — 206 red, 252 green and 155 blue out of 255, or 80.8% / 98.8% / 60.8% by channel.

What is #cefc9b in HSL and HSV?

hsl(89, 94%, 80%) and hsv(88, 38%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cefc9b a light or a dark color?

It is a light color. Relative luminance is 0.8511 and perceived brightness is 90%, so black text on it reaches 18.02:1.

Should I use black or white text on #cefc9b?

Black. It scores 18.02:1 against #cefc9b, versus 1.17:1 for white — AAA at any size.

Is #cefc9b accessible on a white background?

#cefc9b on white scores 1.17:1, which fails WCAG AA at every size. Darken it to #488504 to reach 4.5:1, or #356203 for 7:1.

What is the complementary color of #cefc9b?

#C99BFC sits directly opposite on the wheel. Softer options are the split-complements #9B9DFC and #FA9BFC, which give the same contrast with far less vibration.

What colors go well with #cefc9b?

For interface work: #F8FAF4 as the surface, #D7EDC0 for borders, #759B4B for secondary text, #3002CA as an accent and #437C04 for hover and pressed states. For a palette, the analogous pair #FCFA9B and #9DFC9B stays calm, while #C99BFC is the loudest partner.

What is #cefc9b in CMYK for printing?

cmyk(18%, 0%, 39%, 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 #cefc9b warm or cool?

Neutral — it scores 49 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F1FC9B; nudged cooler, #AAFD9A.

Which Tailwind color is closest to #cefc9b?

The lime family — its 500 step is #84cc16, ΔE2000 15.1 away. That is a visible difference, so define #cefc9b as a custom token rather than reaching for the built-in.

How do I use #cefc9b in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cefc9b] or text-[#cefc9b], 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 #cefc9b with 50% opacity?

rgba(206, 252, 155, 0.5), or #cefc9b80 in eight-digit hex. Over white that composites to #E7FECD; over black, #677E4E.

Is #cefc9b a web-safe color?

No. The nearest web-safe colour is #CCFF99, ΔE2000 1 away. The palette only matters for legacy displays and some email clients now.

What does the color #cefc9b 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 #cefc9b?
