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 #e4fdef

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 #097739
Safe as a 1px border on white
No — use #0CA851

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.

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.

#e4fdef, answered

What color is #e4fdef?

#e4fdef is a pale electric green, closest to Honey Dew (ΔE2000 3.4). It sits at 146° on the hue wheel with 86% saturation and 94% lightness, which reads as cool.

What is the RGB value of #e4fdef?

rgb(228, 253, 239) — 228 red, 253 green and 239 blue out of 255, or 89.4% / 99.2% / 93.7% by channel.

What is #e4fdef in HSL and HSV?

hsl(146, 86%, 94%) and hsv(146, 10%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #e4fdef a light or a dark color?

It is a light color. Relative luminance is 0.9298 and perceived brightness is 96%, so black text on it reaches 19.60:1.

Should I use black or white text on #e4fdef?

Black. It scores 19.60:1 against #e4fdef, versus 1.07:1 for white — AAA at any size.

Is #e4fdef accessible on a white background?

#e4fdef on white scores 1.07:1, which fails WCAG AA at every size. Darken it to #0A8641 to reach 4.5:1, or #076531 for 7:1.

What is the complementary color of #e4fdef?

#FDE4F2 sits directly opposite on the wheel. Softer options are the split-complements #FBE4FD and #FDE4E5, which give the same contrast with far less vibration.

What colors go well with #e4fdef?

For interface work: #F4FAF7 as the surface, #C0EDD4 for borders, #4B9B6E for secondary text, #C507A2 as an accent and #097739 for hover and pressed states. For a palette, the analogous pair #E5FDE4 and #E4FDFB stays calm, while #FDE4F2 is the loudest partner.

What is #e4fdef in CMYK for printing?

cmyk(10%, 0%, 6%, 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 #e4fdef warm or cool?

Cool — it scores 73 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #E4FDE6; nudged cooler, #E4FDF8.

Which Tailwind color is closest to #e4fdef?

The teal family — its 500 step is #14b8a6, ΔE2000 25.6 away. That is a visible difference, so define #e4fdef as a custom token rather than reaching for the built-in.

How do I use #e4fdef in Tailwind CSS?

Inline it as an arbitrary value with bg-[#e4fdef] or text-[#e4fdef], 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 #e4fdef with 50% opacity?

rgba(228, 253, 239, 0.5), or #e4fdef80 in eight-digit hex. Over white that composites to #F2FEF7; over black, #727F78.

Is #e4fdef a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 8.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #e4fdef 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 #e4fdef?
