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 #3cf034

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 #0E7709
Safe as a 1px border on white
No — use #14AC0D

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.

#3cf034, answered

What color is #3cf034?

#3cf034 is a balanced electric green, closest to Lime (ΔE2000 3.7). It sits at 117° on the hue wheel with 86% saturation and 57% lightness, which reads as cool.

What is the RGB value of #3cf034?

rgb(60, 240, 52) — 60 red, 240 green and 52 blue out of 255, or 23.5% / 94.1% / 20.4% by channel.

What is #3cf034 in HSL and HSV?

hsl(117, 86%, 57%) and hsv(117, 78%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #3cf034 a light or a dark color?

It is a light color. Relative luminance is 0.6353 and perceived brightness is 74%, so black text on it reaches 13.71:1.

Should I use black or white text on #3cf034?

Black. It scores 13.71:1 against #3cf034, versus 1.53:1 for white — AAA at any size.

Is #3cf034 accessible on a white background?

#3cf034 on white scores 1.53:1, which fails WCAG AA at every size. Darken it to #0F860A to reach 4.5:1, or #0C6507 for 7:1.

What is the complementary color of #3cf034?

#E834F0 sits directly opposite on the wheel. Softer options are the split-complements #8A34F0 and #F0349A, which give the same contrast with far less vibration.

What colors go well with #3cf034?

For interface work: #F5FAF4 as the surface, #C2EDC0 for borders, #4E9B4B for secondary text, #BB30F4 as an accent and #0E7709 for hover and pressed states. For a palette, the analogous pair #9AF034 and #34F08A stays calm, while #E834F0 is the loudest partner.

What is #3cf034 in CMYK for printing?

cmyk(75%, 0%, 78%, 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 #3cf034 warm or cool?

Cool — it scores 61 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #81F034; nudged cooler, #32F270.

Which Tailwind color is closest to #3cf034?

The lime family — its 500 step is #84cc16, ΔE2000 10.7 away. That is a visible difference, so define #3cf034 as a custom token rather than reaching for the built-in.

How do I use #3cf034 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#3cf034] or text-[#3cf034], 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 #3cf034 with 50% opacity?

rgba(60, 240, 52, 0.5), or #3cf03480 in eight-digit hex. Over white that composites to #9EF89A; over black, #1E781A.

Is #3cf034 a web-safe color?

No. The nearest web-safe colour is #33FF33, ΔE2000 3.2 away. The palette only matters for legacy displays and some email clients now.
