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 #cef97f

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 #517A06
Safe as a 1px border on white
No — use #6DA408

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.

Transparency

What each alpha value actually composites to. The top row is #cef97f 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.

#cef97f, answered

What color is #cef97f?

#cef97f is a light electric green, closest to Green Yellow (ΔE2000 7.6). It sits at 81° on the hue wheel with 91% saturation and 74% lightness, which reads as neutral.

What is the RGB value of #cef97f?

rgb(206, 249, 127) — 206 red, 249 green and 127 blue out of 255, or 80.8% / 97.6% / 49.8% by channel.

What is #cef97f in HSL and HSV?

hsl(81, 91%, 74%) and hsv(81, 49%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cef97f a light or a dark color?

It is a light color. Relative luminance is 0.8241 and perceived brightness is 88%, so black text on it reaches 17.48:1.

Should I use black or white text on #cef97f?

Black. It scores 17.48:1 against #cef97f, versus 1.20:1 for white — AAA at any size.

Is #cef97f accessible on a white background?

#cef97f on white scores 1.20:1, which fails WCAG AA at every size. Darken it to #568206 to reach 4.5:1, or #406005 for 7:1.

What is the complementary color of #cef97f?

#AA7FF9 sits directly opposite on the wheel. Softer options are the split-complements #7F91F9 and #E77FF9, which give the same contrast with far less vibration.

What colors go well with #cef97f?

For interface work: #F8FAF4 as the surface, #DDEDC0 for borders, #7F9B4B for secondary text, #897CFC as an accent and #517A06 for hover and pressed states. For a palette, the analogous pair #F9E77F and #91F97F stays calm, while #AA7FF9 is the loudest partner.

What is #cef97f in CMYK for printing?

cmyk(17%, 0%, 49%, 2%). 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 #cef97f warm or cool?

Neutral — it scores 43 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F9F77F; nudged cooler, #A1FA7E.

Which Tailwind color is closest to #cef97f?

The lime family — its 500 step is #84cc16, ΔE2000 13 away. That is a visible difference, so define #cef97f as a custom token rather than reaching for the built-in.

How do I use #cef97f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cef97f] or text-[#cef97f], 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 #cef97f with 50% opacity?

rgba(206, 249, 127, 0.5), or #cef97f80 in eight-digit hex. Over white that composites to #E7FCBF; over black, #677D40.

Is #cef97f a web-safe color?

No. The nearest web-safe colour is #CCFF66, ΔE2000 3.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #cef97f 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 #cef97f?
