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 #4bbc8f

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 #235D46
Safe as a 1px border on white
No — use #3EA67C

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 #4bbc8f 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.

#4bbc8f, answered

What color is #4bbc8f?

#4bbc8f is a balanced vivid green, closest to Medium Aqua Marine (ΔE2000 5.8). It sits at 156° on the hue wheel with 46% saturation and 52% lightness, which reads as cool.

What is the RGB value of #4bbc8f?

rgb(75, 188, 143) — 75 red, 188 green and 143 blue out of 255, or 29.4% / 73.7% / 56.1% by channel.

What is #4bbc8f in HSL and HSV?

hsl(156, 46%, 52%) and hsv(156, 60%, 74%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #4bbc8f a light or a dark color?

It is a mid-tone. Relative luminance is 0.3945 and perceived brightness is 62%, so black text on it reaches 8.89:1.

Should I use black or white text on #4bbc8f?

Black. It scores 8.89:1 against #4bbc8f, versus 2.36:1 for white — AAA at any size.

Is #4bbc8f accessible on a white background?

#4bbc8f on white scores 2.36:1, which fails WCAG AA at every size. Darken it to #318463 to reach 4.5:1, or #25634A for 7:1.

What is the complementary color of #4bbc8f?

#BC4B78 sits directly opposite on the wheel. Softer options are the split-complements #BC4BB1 and #BC574B, which give the same contrast with far less vibration.

What colors go well with #4bbc8f?

For interface work: #F4FAF8 as the surface, #C4E9DA for borders, #4B9B7B for secondary text, #C14696 as an accent and #235D46 for hover and pressed states. For a palette, the analogous pair #4BBC57 and #4BB1BC stays calm, while #BC4B78 is the loudest partner.

What is #4bbc8f in CMYK for printing?

cmyk(60%, 0%, 24%, 26%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #4bbc8f warm or cool?

Cool — it scores 78 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #4BBC66; nudged cooler, #49BEBB.

Which Tailwind color is closest to #4bbc8f?

The emerald family — its 500 step is #10b981, ΔE2000 3.7 away. That is a visible difference, so define #4bbc8f as a custom token rather than reaching for the built-in.

How do I use #4bbc8f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#4bbc8f] or text-[#4bbc8f], 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 #4bbc8f with 50% opacity?

rgba(75, 188, 143, 0.5), or #4bbc8f80 in eight-digit hex. Over white that composites to #A5DEC7; over black, #265E48.

Is #4bbc8f a web-safe color?

No. The nearest web-safe colour is #33CC99, ΔE2000 4.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #4bbc8f 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 #4bbc8f?
