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 #2fac68

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 #1B643D
Safe as a 1px border on white
No — use #2EA866

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 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.

Transparency

What each alpha value actually composites to. The top row is #2fac68 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.

#2fac68, answered

What color is #2fac68?

#2fac68 is a dark vivid green, closest to Medium Sea Green (ΔE2000 2.3). It sits at 147° on the hue wheel with 57% saturation and 43% lightness, which reads as cool.

What is the RGB value of #2fac68?

rgb(47, 172, 104) — 47 red, 172 green and 104 blue out of 255, or 18.4% / 67.5% / 40.8% by channel.

What is #2fac68 in HSL and HSV?

hsl(147, 57%, 43%) and hsv(147, 73%, 67%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2fac68 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3111 and perceived brightness is 54%, so black text on it reaches 7.22:1.

Should I use black or white text on #2fac68?

Black. It scores 7.22:1 against #2fac68, versus 2.91:1 for white — AAA at any size.

Is #2fac68 accessible on a white background?

#2fac68 on white scores 2.91:1, which fails WCAG AA at every size. Darken it to #248450 to reach 4.5:1, or #1B643C for 7:1.

What is the complementary color of #2fac68?

#AC2F73 sits directly opposite on the wheel. Softer options are the split-complements #A62FAC and #AC2F34, which give the same contrast with far less vibration.

What colors go well with #2fac68?

For interface work: #F4FAF7 as the surface, #C0EDD4 for borders, #4B9B6F for secondary text, #B02B95 as an accent and #1B643D for hover and pressed states. For a palette, the analogous pair #34AC2F and #2FACA6 stays calm, while #AC2F73 is the loudest partner.

What is #2fac68 in CMYK for printing?

cmyk(73%, 0%, 40%, 33%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #2fac68 warm or cool?

Cool — it scores 74 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #2FAC3A; nudged cooler, #2DAE97.

Which Tailwind color is closest to #2fac68?

The emerald family — its 500 step is #10b981, ΔE2000 5.3 away. That is a visible difference, so define #2fac68 as a custom token rather than reaching for the built-in.

How do I use #2fac68 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2fac68] or text-[#2fac68], 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 #2fac68 with 50% opacity?

rgba(47, 172, 104, 0.5), or #2fac6880 in eight-digit hex. Over white that composites to #97D6B4; over black, #185634.

Is #2fac68 a web-safe color?

No. The nearest web-safe colour is #339966, ΔE2000 6.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #2fac68 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 #2fac68?
