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 #cdfeda

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 #027D23
Safe as a 1px border on white
No — use #03AA30

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.

Transparency

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

#cdfeda, answered

What color is #cdfeda?

#cdfeda is a pale electric green, closest to Aqua Marine (ΔE2000 10.2). It sits at 136° on the hue wheel with 96% saturation and 90% lightness, which reads as cool.

What is the RGB value of #cdfeda?

rgb(205, 254, 218) — 205 red, 254 green and 218 blue out of 255, or 80.4% / 99.6% / 85.5% by channel.

What is #cdfeda in HSL and HSV?

hsl(136, 96%, 90%) and hsv(136, 19%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cdfeda a light or a dark color?

It is a light color. Relative luminance is 0.8892 and perceived brightness is 93%, so black text on it reaches 18.78:1.

Should I use black or white text on #cdfeda?

Black. It scores 18.78:1 against #cdfeda, versus 1.12:1 for white — AAA at any size.

Is #cdfeda accessible on a white background?

#cdfeda on white scores 1.12:1, which fails WCAG AA at every size. Darken it to #038726 to reach 4.5:1, or #02641C for 7:1.

What is the complementary color of #cdfeda?

#FECDF1 sits directly opposite on the wheel. Softer options are the split-complements #F2CDFE and #FECDD9, which give the same contrast with far less vibration.

What colors go well with #cdfeda?

For interface work: #F4FAF6 as the surface, #C0EDCC for borders, #4B9B60 for secondary text, #CC00C8 as an accent and #027D23 for hover and pressed states. For a palette, the analogous pair #D9FECD and #CDFEF2 stays calm, while #FECDF1 is the loudest partner.

What is #cdfeda in CMYK for printing?

cmyk(19%, 0%, 14%, 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 #cdfeda warm or cool?

Cool — it scores 69 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D2FECD; nudged cooler, #CCFFEC.

Which Tailwind color is closest to #cdfeda?

The emerald family — its 500 step is #10b981, ΔE2000 22.6 away. That is a visible difference, so define #cdfeda as a custom token rather than reaching for the built-in.

How do I use #cdfeda in Tailwind CSS?

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

rgba(205, 254, 218, 0.5), or #cdfeda80 in eight-digit hex. Over white that composites to #E6FFED; over black, #677F6D.

Is #cdfeda a web-safe color?

No. The nearest web-safe colour is #CCFFCC, ΔE2000 3.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #cdfeda 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 #cdfeda?

The safest is same-hue elevation: linear-gradient(135deg, #EBFFF0, #cdfeda 45%, #027D23). For more colour, a short hue run to #AFFCFD keeps it rich without turning muddy.
