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 #cefac9

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 #16750B
Safe as a 1px border on white
No — use #1FAA10

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 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.

#cefac9, answered

What color is #cefac9?

#cefac9 is a pale electric green, closest to Pale Green (ΔE2000 10.7). It sits at 114° on the hue wheel with 83% saturation and 88% lightness, which reads as cool.

What is the RGB value of #cefac9?

rgb(206, 250, 201) — 206 red, 250 green and 201 blue out of 255, or 80.8% / 98% / 78.8% by channel.

What is #cefac9 in HSL and HSV?

hsl(114, 83%, 88%) and hsv(114, 20%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cefac9 a light or a dark color?

It is a light color. Relative luminance is 0.8571 and perceived brightness is 91%, so black text on it reaches 18.14:1.

Should I use black or white text on #cefac9?

Black. It scores 18.14:1 against #cefac9, versus 1.16:1 for white — AAA at any size.

Is #cefac9 accessible on a white background?

#cefac9 on white scores 1.16:1, which fails WCAG AA at every size. Darken it to #19890D to reach 4.5:1, or #126409 for 7:1.

What is the complementary color of #cefac9?

#F5C9FA sits directly opposite on the wheel. Softer options are the split-complements #DCC9FA and #FAC9E6, which give the same contrast with far less vibration.

What colors go well with #cefac9?

For interface work: #F5FAF4 as the surface, #C4EDC0 for borders, #539B4B for secondary text, #800EBE as an accent and #16750B for hover and pressed states. For a palette, the analogous pair #E6FAC9 and #C9FADC stays calm, while #F5C9FA is the loudest partner.

What is #cefac9 in CMYK for printing?

cmyk(18%, 0%, 20%, 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 #cefac9 warm or cool?

Cool — it scores 60 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #E0FAC9; nudged cooler, #C8FBD6.

Which Tailwind color is closest to #cefac9?

The green family — its 500 step is #22c55e, ΔE2000 21 away. That is a visible difference, so define #cefac9 as a custom token rather than reaching for the built-in.

How do I use #cefac9 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cefac9] or text-[#cefac9], 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 #cefac9 with 50% opacity?

rgba(206, 250, 201, 0.5), or #cefac980 in eight-digit hex. Over white that composites to #E7FDE4; over black, #677D65.

Is #cefac9 a web-safe color?

No. The nearest web-safe colour is #CCFFCC, ΔE2000 1.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #cefac9 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 #cefac9?

The safest is same-hue elevation: linear-gradient(135deg, #EEFDEC, #cefac9 45%, #16750B). For more colour, a short hue run to #ADF7DD keeps it rich without turning muddy.
