How to use #4fd796

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 #186841
Safe as a 1px border on white
No — use #26A96A

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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 #4fd796 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.

#4fd796, answered

What color is #4fd796?

#4fd796 is a balanced vivid green, closest to Medium Aqua Marine (ΔE2000 7.1). It sits at 151° on the hue wheel with 63% saturation and 58% lightness, which reads as cool.

What is the RGB value of #4fd796?

rgb(79, 215, 150) — 79 red, 215 green and 150 blue out of 255, or 31% / 84.3% / 58.8% by channel.

What is #4fd796 in HSL and HSV?

hsl(151, 63%, 58%) and hsv(151, 63%, 84%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #4fd796 a light or a dark color?

It is a light color. Relative luminance is 0.5247 and perceived brightness is 70%, so black text on it reaches 11.49:1.

Should I use black or white text on #4fd796?

Black. It scores 11.49:1 against #4fd796, versus 1.83:1 for white — AAA at any size.

Is #4fd796 accessible on a white background?

#4fd796 on white scores 1.83:1, which fails WCAG AA at every size. Darken it to #1E8353 to reach 4.5:1, or #16623E for 7:1.

What is the complementary color of #4fd796?

#D74F90 sits directly opposite on the wheel. Softer options are the split-complements #D74FD4 and #D7524F, which give the same contrast with far less vibration.

What colors go well with #4fd796?

For interface work: #F4FAF7 as the surface, #C0EDD7 for borders, #4B9B74 for secondary text, #DB4AB4 as an accent and #186841 for hover and pressed states. For a palette, the analogous pair #4FD752 and #4FD4D7 stays calm, while #D74F90 is the loudest partner.

What is #4fd796 in CMYK for printing?

cmyk(63%, 0%, 30%, 16%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #4fd796 warm or cool?

Cool — it scores 76 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #4FD764; nudged cooler, #4DD9C9.

Which Tailwind color is closest to #4fd796?

The emerald family — its 500 step is #10b981, ΔE2000 8.3 away. That is a visible difference, so define #4fd796 as a custom token rather than reaching for the built-in.

How do I use #4fd796 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#4fd796] or text-[#4fd796], 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 #4fd796 with 50% opacity?

rgba(79, 215, 150, 0.5), or #4fd79680 in eight-digit hex. Over white that composites to #A7EBCB; over black, #286C4B.

Is #4fd796 a web-safe color?

No. The nearest web-safe colour is #66CC99, ΔE2000 3.9 away. The palette only matters for legacy displays and some email clients now.
