How to use #6cf85b

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 #127A05
Safe as a 1px border on white
No — use #19A907

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 lightness keeps it airy and approachable.

Worth knowing

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

#6cf85b, answered

What color is #6cf85b?

#6cf85b is a light electric green, closest to Lime (ΔE2000 5). It sits at 114° on the hue wheel with 92% saturation and 67% lightness, which reads as cool.

What is the RGB value of #6cf85b?

rgb(108, 248, 91) — 108 red, 248 green and 91 blue out of 255, or 42.4% / 97.3% / 35.7% by channel.

What is #6cf85b in HSL and HSV?

hsl(114, 92%, 67%) and hsv(114, 63%, 97%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6cf85b a light or a dark color?

It is a light color. Relative luminance is 0.7108 and perceived brightness is 79%, so black text on it reaches 15.22:1.

Should I use black or white text on #6cf85b?

Black. It scores 15.22:1 against #6cf85b, versus 1.38:1 for white — AAA at any size.

Is #6cf85b accessible on a white background?

#6cf85b on white scores 1.38:1, which fails WCAG AA at every size. Darken it to #148606 to reach 4.5:1, or #0F6404 for 7:1.

What is the complementary color of #6cf85b?

#E75BF8 sits directly opposite on the wheel. Softer options are the split-complements #995BF8 and #F85BBB, which give the same contrast with far less vibration.

What colors go well with #6cf85b?

For interface work: #F5FAF4 as the surface, #C5EDC0 for borders, #539B4B for secondary text, #C158FB as an accent and #127A05 for hover and pressed states. For a palette, the analogous pair #BBF85B and #5BF899 stays calm, while #E75BF8 is the loudest partner.

What is #6cf85b in CMYK for printing?

cmyk(57%, 0%, 63%, 3%). 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 #6cf85b warm or cool?

Cool — it scores 60 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A6F85B; nudged cooler, #59FA83.

Which Tailwind color is closest to #6cf85b?

The lime family — its 500 step is #84cc16, ΔE2000 11.7 away. That is a visible difference, so define #6cf85b as a custom token rather than reaching for the built-in.

How do I use #6cf85b in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6cf85b] or text-[#6cf85b], 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 #6cf85b with 50% opacity?

rgba(108, 248, 91, 0.5), or #6cf85b80 in eight-digit hex. Over white that composites to #B6FCAD; over black, #367C2E.

Is #6cf85b a web-safe color?

No. The nearest web-safe colour is #66FF66, ΔE2000 1.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #6cf85b mean?
