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 #e4fff2

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 #008042
Safe as a 1px border on white
No — use #00A756

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.

#e4fff2, answered

What color is #e4fff2?

#e4fff2 is a pale electric green, closest to Honey Dew (ΔE2000 4). It sits at 151° on the hue wheel with 100% saturation and 95% lightness, which reads as cool.

What is the RGB value of #e4fff2?

rgb(228, 255, 242) — 228 red, 255 green and 242 blue out of 255, or 89.4% / 100% / 94.9% by channel.

What is #e4fff2 in HSL and HSV?

hsl(151, 100%, 95%) and hsv(151, 11%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #e4fff2 a light or a dark color?

It is a light color. Relative luminance is 0.9442 and perceived brightness is 96%, so black text on it reaches 19.88:1.

Should I use black or white text on #e4fff2?

Black. It scores 19.88:1 against #e4fff2, versus 1.06:1 for white — AAA at any size.

Is #e4fff2 accessible on a white background?

#e4fff2 on white scores 1.06:1, which fails WCAG AA at every size. Darken it to #008847 to reach 4.5:1, or #006434 for 7:1.

What is the complementary color of #e4fff2?

#FFE4F1 sits directly opposite on the wheel. Softer options are the split-complements #FFE4FF and #FFE4E4, which give the same contrast with far less vibration.

What colors go well with #e4fff2?

For interface work: #F4FAF7 as the surface, #C0EDD7 for borders, #4B9B74 for secondary text, #CC0097 as an accent and #008042 for hover and pressed states. For a palette, the analogous pair #E4FFE4 and #E4FFFF stays calm, while #FFE4F1 is the loudest partner.

What is #e4fff2 in CMYK for printing?

cmyk(11%, 0%, 5%, 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 #e4fff2 warm or cool?

Cool — it scores 75 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #E4FFE8; nudged cooler, #E4FFFC.

Which Tailwind color is closest to #e4fff2?

The teal family — its 500 step is #14b8a6, ΔE2000 25.6 away. That is a visible difference, so define #e4fff2 as a custom token rather than reaching for the built-in.

How do I use #e4fff2 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#e4fff2] or text-[#e4fff2], 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 #e4fff2 with 50% opacity?

rgba(228, 255, 242, 0.5), or #e4fff280 in eight-digit hex. Over white that composites to #F2FFF9; over black, #728079.

Is #e4fff2 a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 7.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #e4fff2 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 #e4fff2?

The safest is same-hue elevation: linear-gradient(135deg, #EBFFF5, #e4fff2 45%, #008042). For more colour, a short hue run to #C5F0FF keeps it rich without turning muddy.
