  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text on black or near-black surfaces
  • 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

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.

With almost no chroma left, the family association is barely present; treat it as a neutral that happens to lean this way. 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.

#2f342b, answered

What color is #2f342b?

#2f342b is a deep muted green, closest to Dark Slate Gray (ΔE2000 12.9). It sits at 93° on the hue wheel with 10% saturation and 19% lightness, which reads as neutral.

What is the RGB value of #2f342b?

rgb(47, 52, 43) — 47 red, 52 green and 43 blue out of 255, or 18.4% / 20.4% / 16.9% by channel.

What is #2f342b in HSL and HSV?

hsl(93, 10%, 19%) and hsv(93, 17%, 20%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #2f342b a light or a dark color?

It is a dark color. Relative luminance is 0.0323 and perceived brightness is 19%, so white text on it reaches 12.75:1.

Should I use black or white text on #2f342b?

White. It scores 12.75:1 against #2f342b, versus 1.65:1 for black — AAA at any size.

Is #2f342b accessible on a white background?

#2f342b on white scores 12.75:1, which clears AAA at every size.

What is the complementary color of #2f342b?

#302B34 sits directly opposite on the wheel. Softer options are the split-complements #2B2B34 and #342B33, which give the same contrast with far less vibration.

What colors go well with #2f342b?

For interface work: #F7F8F7 as the surface, #D6DAD2 for borders, #727E68 for secondary text, #2D2936 as an accent and #3F463A for hover and pressed states. For a palette, the analogous pair #33342B and #2B342B stays calm, while #302B34 is the loudest partner.

What is #2f342b in CMYK for printing?

cmyk(10%, 0%, 17%, 80%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #2f342b warm or cool?

Neutral — it scores 50 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #3C342D; nudged cooler, #242A30.

Which Tailwind color is closest to #2f342b?

The neutral family — its 500 step is #737373, ΔE2000 23.5 away. That is a visible difference, so define #2f342b as a custom token rather than reaching for the built-in.

How do I use #2f342b in Tailwind CSS?

Inline it as an arbitrary value with bg-[#2f342b] or text-[#2f342b], 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 #2f342b with 50% opacity?

rgba(47, 52, 43, 0.5), or #2f342b80 in eight-digit hex. Over white that composites to #979A95; over black, #181A16.

Is #2f342b a web-safe color?

No. The nearest web-safe colour is #333333, ΔE2000 6.8 away. The palette only matters for legacy displays and some email clients now.
