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 #8ffe13

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 #437F01
Safe as a 1px border on white
No — use #58A501

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.

Transparency

What each alpha value actually composites to. The top row is #8ffe13 over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

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.

#8ffe13, answered

What color is #8ffe13?

#8ffe13 is a balanced electric green, closest to Chartreuse (ΔE2000 1.4). It sits at 88° on the hue wheel with 99% saturation and 54% lightness, which reads as neutral.

What is the RGB value of #8ffe13?

rgb(143, 254, 19) — 143 red, 254 green and 19 blue out of 255, or 56.1% / 99.6% / 7.5% by channel.

What is #8ffe13 in HSL and HSV?

hsl(88, 99%, 54%) and hsv(88, 93%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8ffe13 a light or a dark color?

It is a light color. Relative luminance is 0.7677 and perceived brightness is 82%, so black text on it reaches 16.35:1.

Should I use black or white text on #8ffe13?

Black. It scores 16.35:1 against #8ffe13, versus 1.28:1 for white — AAA at any size.

Is #8ffe13 accessible on a white background?

#8ffe13 on white scores 1.28:1, which fails WCAG AA at every size. Darken it to #458201 to reach 4.5:1, or #356300 for 7:1.

What is the complementary color of #8ffe13?

#8213FE sits directly opposite on the wheel. Softer options are the split-complements #1319FE and #F713FE, which give the same contrast with far less vibration.

What colors go well with #8ffe13?

For interface work: #F8FAF4 as the surface, #D7EDC0 for borders, #759B4B for secondary text, #4612FF as an accent and #437F01 for hover and pressed states. For a palette, the analogous pair #FEF713 and #19FE13 stays calm, while #8213FE is the loudest partner.

What is #8ffe13 in CMYK for printing?

cmyk(44%, 0%, 93%, 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 #8ffe13 warm or cool?

Neutral — it scores 49 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #E5FE13; nudged cooler, #38FF12.

Which Tailwind color is closest to #8ffe13?

The lime family — its 500 step is #84cc16, ΔE2000 11.2 away. That is a visible difference, so define #8ffe13 as a custom token rather than reaching for the built-in.

How do I use #8ffe13 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8ffe13] or text-[#8ffe13], 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 #8ffe13 with 50% opacity?

rgba(143, 254, 19, 0.5), or #8ffe1380 in eight-digit hex. Over white that composites to #C7FF89; over black, #487F0A.

Is #8ffe13 a web-safe color?

No. The nearest web-safe colour is #99FF00, ΔE2000 1.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #8ffe13 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 #8ffe13?
