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 #4fba08

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 #347A05
Safe as a 1px border on white
No — use #47A607

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 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.

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.

#4fba08, answered

What color is #4fba08?

#4fba08 is a dark electric green, closest to Lime Green (ΔE2000 5.8). It sits at 96° on the hue wheel with 92% saturation and 38% lightness, which reads as neutral.

What is the RGB value of #4fba08?

rgb(79, 186, 8) — 79 red, 186 green and 8 blue out of 255, or 31% / 72.9% / 3.1% by channel.

What is #4fba08 in HSL and HSV?

hsl(96, 92%, 38%) and hsv(96, 96%, 73%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #4fba08 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3680 and perceived brightness is 58%, so black text on it reaches 8.36:1.

Should I use black or white text on #4fba08?

Black. It scores 8.36:1 against #4fba08, versus 2.51:1 for white — AAA at any size.

Is #4fba08 accessible on a white background?

#4fba08 on white scores 2.51:1, which fails WCAG AA at every size. Darken it to #388406 to reach 4.5:1, or #296204 for 7:1.

What is the complementary color of #4fba08?

#7308BA sits directly opposite on the wheel. Softer options are the split-complements #1A08BA and #BA08A8, which give the same contrast with far less vibration.

What colors go well with #4fba08?

For interface work: #F7FAF4 as the surface, #D2EDC0 for borders, #6B9B4B for secondary text, #4504BE as an accent and #347A05 for hover and pressed states. For a palette, the analogous pair #A8BA08 and #08BA1A stays calm, while #7308BA is the loudest partner.

What is #4fba08 in CMYK for printing?

cmyk(58%, 0%, 96%, 27%). 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 #4fba08 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 #90BA08; nudged cooler, #0CBC06.

Which Tailwind color is closest to #4fba08?

The lime family — its 500 step is #84cc16, ΔE2000 7.4 away. That is a visible difference, so define #4fba08 as a custom token rather than reaching for the built-in.

How do I use #4fba08 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#4fba08] or text-[#4fba08], 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 #4fba08 with 50% opacity?

rgba(79, 186, 8, 0.5), or #4fba0880 in eight-digit hex. Over white that composites to #A7DD84; over black, #285D04.

Is #4fba08 a web-safe color?

No. The nearest web-safe colour is #66CC00, ΔE2000 5.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #4fba08 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.
