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 #e5feec

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 #057B26
Safe as a 1px border on white
No — use #07AA34

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.

#e5feec, answered

What color is #e5feec?

#e5feec is a pale electric green, closest to Honey Dew (ΔE2000 3.5). It sits at 137° on the hue wheel with 93% saturation and 95% lightness, which reads as cool.

What is the RGB value of #e5feec?

rgb(229, 254, 236) — 229 red, 254 green and 236 blue out of 255, or 89.8% / 99.6% / 92.5% by channel.

What is #e5feec in HSL and HSV?

hsl(137, 93%, 95%) and hsv(137, 10%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #e5feec a light or a dark color?

It is a light color. Relative luminance is 0.9360 and perceived brightness is 96%, so black text on it reaches 19.72:1.

Should I use black or white text on #e5feec?

Black. It scores 19.72:1 against #e5feec, versus 1.06:1 for white — AAA at any size.

Is #e5feec accessible on a white background?

#e5feec on white scores 1.06:1, which fails WCAG AA at every size. Darken it to #05882A to reach 4.5:1, or #04661F for 7:1.

What is the complementary color of #e5feec?

#FEE5F7 sits directly opposite on the wheel. Softer options are the split-complements #F8E5FE and #FEE5EA, which give the same contrast with far less vibration.

What colors go well with #e5feec?

For interface work: #F4FAF6 as the surface, #C0EDCC for borders, #4B9B61 for secondary text, #CC00C5 as an accent and #057B26 for hover and pressed states. For a palette, the analogous pair #EAFEE5 and #E5FEF8 stays calm, while #FEE5F7 is the loudest partner.

What is #e5feec in CMYK for printing?

cmyk(10%, 0%, 7%, 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 #e5feec warm or cool?

Cool — it scores 70 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #E7FEE5; nudged cooler, #E5FEF5.

Which Tailwind color is closest to #e5feec?

The teal family — its 500 step is #14b8a6, ΔE2000 25.8 away. That is a visible difference, so define #e5feec as a custom token rather than reaching for the built-in.

How do I use #e5feec in Tailwind CSS?

Inline it as an arbitrary value with bg-[#e5feec] or text-[#e5feec], 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 #e5feec with 50% opacity?

rgba(229, 254, 236, 0.5), or #e5feec80 in eight-digit hex. Over white that composites to #F2FFF6; over black, #737F76.

Is #e5feec a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 9.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #e5feec 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 #e5feec?
