How to use #8eb11f

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
  • Headers, footers and dark-mode surfaces
  • 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
  • Black 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 #576D13
Safe as a 1px border on white
No — use #80A01C

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The low lightness adds weight and formality.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

#8eb11f, answered

What color is #8eb11f?

#8eb11f is a dark vivid green, closest to Yellow Green (ΔE2000 7.3). It sits at 74° on the hue wheel with 70% saturation and 41% lightness, which reads as warm.

What is the RGB value of #8eb11f?

rgb(142, 177, 31) — 142 red, 177 green and 31 blue out of 255, or 55.7% / 69.4% / 12.2% by channel.

What is #8eb11f in HSL and HSV?

hsl(74, 70%, 41%) and hsv(74, 82%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8eb11f a light or a dark color?

It is a mid-tone. Relative luminance is 0.3729 and perceived brightness is 61%, so black text on it reaches 8.46:1.

Should I use black or white text on #8eb11f?

Black. It scores 8.46:1 against #8eb11f, versus 2.48:1 for white — AAA at any size.

Is #8eb11f accessible on a white background?

#8eb11f on white scores 2.48:1, which fails WCAG AA at every size. Darken it to #647D16 to reach 4.5:1, or #4C5F11 for 7:1.

What is the complementary color of #8eb11f?

#421FB1 sits directly opposite on the wheel. Softer options are the split-complements #1F45B1 and #8B1FB1, which give the same contrast with far less vibration.

What colors go well with #8eb11f?

For interface work: #F9FAF4 as the surface, #E2EDC0 for borders, #889B4B for secondary text, #1B1CB5 as an accent and #576D13 for hover and pressed states. For a palette, the analogous pair #B18B1F and #45B11F stays calm, while #421FB1 is the loudest partner.

What is #8eb11f in CMYK for printing?

cmyk(20%, 0%, 83%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #8eb11f warm or cool?

Warm — it scores 37 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B19F1F; nudged cooler, #58B31D.

Which Tailwind color is closest to #8eb11f?

The lime family — its 500 step is #84cc16, ΔE2000 7.9 away. That is a visible difference, so define #8eb11f as a custom token rather than reaching for the built-in.

How do I use #8eb11f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8eb11f] or text-[#8eb11f], 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 #8eb11f with 50% opacity?

rgba(142, 177, 31, 0.5), or #8eb11f80 in eight-digit hex. Over white that composites to #C7D88F; over black, #475910.

Is #8eb11f a web-safe color?

No. The nearest web-safe colour is #999933, ΔE2000 9.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #8eb11f mean?
