How to use #8cf151

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #317609
Safe as a 1px border on white
No — use #45A60D

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 mid lightness keeps it versatile in both themes.

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.

#8cf151, answered

What color is #8cf151?

#8cf151 is a balanced electric green, closest to Lawn Green (ΔE2000 4.6). It sits at 98° on the hue wheel with 85% saturation and 63% lightness, which reads as neutral.

What is the RGB value of #8cf151?

rgb(140, 241, 81) — 140 red, 241 green and 81 blue out of 255, or 54.9% / 94.5% / 31.8% by channel.

What is #8cf151 in HSL and HSV?

hsl(98, 85%, 63%) and hsv(98, 66%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8cf151 a light or a dark color?

It is a light color. Relative luminance is 0.6908 and perceived brightness is 79%, so black text on it reaches 14.82:1.

Should I use black or white text on #8cf151?

Black. It scores 14.82:1 against #8cf151, versus 1.42:1 for white — AAA at any size.

Is #8cf151 accessible on a white background?

#8cf151 on white scores 1.42:1, which fails WCAG AA at every size. Darken it to #38850B to reach 4.5:1, or #2A6408 for 7:1.

What is the complementary color of #8cf151?

#B651F1 sits directly opposite on the wheel. Softer options are the split-complements #6651F1 and #F151DC, which give the same contrast with far less vibration.

What colors go well with #8cf151?

For interface work: #F7FAF4 as the surface, #D0EDC0 for borders, #689B4B for secondary text, #8D4DF5 as an accent and #317609 for hover and pressed states. For a palette, the analogous pair #DCF151 and #51F166 stays calm, while #B651F1 is the loudest partner.

What is #8cf151 in CMYK for printing?

cmyk(42%, 0%, 66%, 6%). 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 #8cf151 warm or cool?

Neutral — it scores 53 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C7F151; nudged cooler, #4FF34F.

Which Tailwind color is closest to #8cf151?

The lime family — its 500 step is #84cc16, ΔE2000 9.1 away. That is a visible difference, so define #8cf151 as a custom token rather than reaching for the built-in.

How do I use #8cf151 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8cf151] or text-[#8cf151], 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 #8cf151 with 50% opacity?

rgba(140, 241, 81, 0.5), or #8cf15180 in eight-digit hex. Over white that composites to #C6F8A8; over black, #467929.

Is #8cf151 a web-safe color?

No. The nearest web-safe colour is #99FF66, ΔE2000 3.2 away. The palette only matters for legacy displays and some email clients now.
