  • 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.

#3b3f2f, answered

What color is #3b3f2f?

#3b3f2f is a deep muted green, closest to Dark Slate Gray (ΔE2000 13.1). It sits at 75° on the hue wheel with 15% saturation and 22% lightness, which reads as neutral.

What is the RGB value of #3b3f2f?

rgb(59, 63, 47) — 59 red, 63 green and 47 blue out of 255, or 23.1% / 24.7% / 18.4% by channel.

What is #3b3f2f in HSL and HSV?

hsl(75, 15%, 22%) and hsv(75, 25%, 25%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #3b3f2f a light or a dark color?

It is a dark color. Relative luminance is 0.0469 and perceived brightness is 24%, so white text on it reaches 10.84:1.

Should I use black or white text on #3b3f2f?

White. It scores 10.84:1 against #3b3f2f, versus 1.94:1 for black — AAA at any size.

Is #3b3f2f accessible on a white background?

#3b3f2f on white scores 10.84:1, which clears AAA at every size.

What is the complementary color of #3b3f2f?

#332F3F sits directly opposite on the wheel. Softer options are the split-complements #2F333F and #3B2F3F, which give the same contrast with far less vibration.

What colors go well with #3b3f2f?

For interface work: #F8F8F6 as the surface, #D9DCD0 for borders, #7B8362 for secondary text, #2D2D41 as an accent and #444937 for hover and pressed states. For a palette, the analogous pair #3F3B2F and #333F2F stays calm, while #332F3F is the loudest partner.

What is #3b3f2f in CMYK for printing?

cmyk(6%, 0%, 25%, 75%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #3b3f2f warm or cool?

Neutral — it scores 45 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #3F3D2F; nudged cooler, #35402E.

Which Tailwind color is closest to #3b3f2f?

The stone family — its 500 step is #78716c, ΔE2000 21.2 away. That is a visible difference, so define #3b3f2f as a custom token rather than reaching for the built-in.

How do I use #3b3f2f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#3b3f2f] or text-[#3b3f2f], 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 #3b3f2f with 50% opacity?

rgba(59, 63, 47, 0.5), or #3b3f2f80 in eight-digit hex. Over white that composites to #9D9F97; over black, #1E2018.

Is #3b3f2f a web-safe color?
