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 #cef3c5

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 #266A16
Safe as a 1px border on white
No — use #3EAA23

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The high lightness makes it recede — a surface colour rather than a statement.

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.

#cef3c5, answered

What color is #cef3c5?

#cef3c5 is a pale vivid green, closest to Light Goldenrod Yellow (ΔE2000 10.5). It sits at 108° on the hue wheel with 66% saturation and 86% lightness, which reads as neutral.

What is the RGB value of #cef3c5?

rgb(206, 243, 197) — 206 red, 243 green and 197 blue out of 255, or 80.8% / 95.3% / 77.3% by channel.

What is #cef3c5 in HSL and HSV?

hsl(108, 66%, 86%) and hsv(108, 19%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cef3c5 a light or a dark color?

It is a light color. Relative luminance is 0.8125 and perceived brightness is 89%, so black text on it reaches 17.25:1.

Should I use black or white text on #cef3c5?

Black. It scores 17.25:1 against #cef3c5, versus 1.22:1 for white — AAA at any size.

Is #cef3c5 accessible on a white background?

#cef3c5 on white scores 1.22:1, which fails WCAG AA at every size. Darken it to #31881C to reach 4.5:1, or #246214 for 7:1.

What is the complementary color of #cef3c5?

#EAC5F3 sits directly opposite on the wheel. Softer options are the split-complements #D3C5F3 and #F3C5E5, which give the same contrast with far less vibration.

What colors go well with #cef3c5?

For interface work: #F5FAF4 as the surface, #C9EDC0 for borders, #5A9B4B for secondary text, #6F20AC as an accent and #266A16 for hover and pressed states. For a palette, the analogous pair #E5F3C5 and #C5F3D3 stays calm, while #EAC5F3 is the loudest partner.

What is #cef3c5 in CMYK for printing?

cmyk(15%, 0%, 19%, 5%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #cef3c5 warm or cool?

Neutral — it scores 58 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DFF3C5; nudged cooler, #C4F4CD.

Which Tailwind color is closest to #cef3c5?

The green family — its 500 step is #22c55e, ΔE2000 20.9 away. That is a visible difference, so define #cef3c5 as a custom token rather than reaching for the built-in.

How do I use #cef3c5 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cef3c5] or text-[#cef3c5], 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 #cef3c5 with 50% opacity?

rgba(206, 243, 197, 0.5), or #cef3c580 in eight-digit hex. Over white that composites to #E7F9E2; over black, #677A63.

Is #cef3c5 a web-safe color?

No. The nearest web-safe colour is #CCFFCC, ΔE2000 3.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #cef3c5 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.
