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 #2bc08f

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
  • Thin strokes and 1px borders — they disappear on light UI
  • 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 #17684E
Safe as a 1px border on white
No — use #25A77D

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

cleantechnicalfreshclinical

Cyan reads as water, air and infrastructure: cool, hygienic, engineered.

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

At high lightness it disappears into white surfaces and thin strokes vanish entirely.

Transparency

What each alpha value actually composites to. The top row is #2bc08f 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.

#2bc08f, answered

What color is #2bc08f?

#2bc08f is a balanced vivid cyan, closest to Medium Sea Green (ΔE2000 6.1). It sits at 160° on the hue wheel with 63% saturation and 46% lightness, which reads as cool.

What is the RGB value of #2bc08f?

rgb(43, 192, 143) — 43 red, 192 green and 143 blue out of 255, or 16.9% / 75.3% / 56.1% by channel.

What is #2bc08f in HSL and HSV?

hsl(160, 63%, 46%) and hsv(160, 78%, 75%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2bc08f a light or a dark color?

It is a mid-tone. Relative luminance is 0.4020 and perceived brightness is 61%, so black text on it reaches 9.04:1.

Should I use black or white text on #2bc08f?

Black. It scores 9.04:1 against #2bc08f, versus 2.32:1 for white — AAA at any size.

Is #2bc08f accessible on a white background?

#2bc08f on white scores 2.32:1, which fails WCAG AA at every size. Darken it to #1E8664 to reach 4.5:1, or #16644B for 7:1.

What is the complementary color of #2bc08f?

#C02B5C sits directly opposite on the wheel. Softer options are the split-complements #C02BA6 and #C0452B, which give the same contrast with far less vibration.

What colors go well with #2bc08f?

For interface work: #F4FAF8 as the surface, #C0EDDE for borders, #4B9B81 for secondary text, #C52682 as an accent and #17684E for hover and pressed states. For a palette, the analogous pair #2BC045 and #2BA6C0 stays calm, while #C02B5C is the loudest partner.

What is #2bc08f in CMYK for printing?

cmyk(78%, 0%, 26%, 25%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #2bc08f warm or cool?

Cool — it scores 79 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2BC058; nudged cooler, #29BDC2.

Which Tailwind color is closest to #2bc08f?

The emerald family — its 500 step is #10b981, ΔE2000 2.8 away. That is close enough to swap in without anyone noticing.

How do I use #2bc08f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2bc08f] or text-[#2bc08f], 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 #2bc08f with 50% opacity?

rgba(43, 192, 143, 0.5), or #2bc08f80 in eight-digit hex. Over white that composites to #95E0C7; over black, #166048.

Is #2bc08f a web-safe color?

No. The nearest web-safe colour is #33CC99, ΔE2000 3.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #2bc08f mean?
