Use with care
  • 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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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.

#367f4f, answered

What color is #367f4f?

#367f4f is a dark soft green, closest to Sea Green (ΔE2000 4.4). It sits at 141° on the hue wheel with 40% saturation and 36% lightness, which reads as cool.

What is the RGB value of #367f4f?

rgb(54, 127, 79) — 54 red, 127 green and 79 blue out of 255, or 21.2% / 49.8% / 31% by channel.

What is #367f4f in HSL and HSV?

hsl(141, 40%, 36%) and hsv(141, 57%, 50%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #367f4f a light or a dark color?

It is a dark color. Relative luminance is 0.1653 and perceived brightness is 41%, so white text on it reaches 4.88:1.

Should I use black or white text on #367f4f?

White. It scores 4.88:1 against #367f4f, versus 4.31:1 for black — AA at any size.

Is #367f4f accessible on a white background?

#367f4f on white scores 4.88:1, which clears AA at every size but not AAA.

What is the complementary color of #367f4f?

#7F3666 sits directly opposite on the wheel. Softer options are the split-complements #73367F and #7F3642, which give the same contrast with far less vibration.

What colors go well with #367f4f?

For interface work: #F4FAF6 as the surface, #C6E7D1 for borders, #4B9B66 for secondary text, #83327B as an accent and #265938 for hover and pressed states. For a palette, the analogous pair #427F36 and #367F73 stays calm, while #7F3666 is the loudest partner.

What is #367f4f in CMYK for printing?

cmyk(58%, 0%, 38%, 50%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #367f4f warm or cool?

Cool — it scores 71 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #387F36; nudged cooler, #34816A.

Which Tailwind color is closest to #367f4f?

The emerald family — its 500 step is #10b981, ΔE2000 18.8 away. That is a visible difference, so define #367f4f as a custom token rather than reaching for the built-in.

How do I use #367f4f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#367f4f] or text-[#367f4f], 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 #367f4f with 50% opacity?

rgba(54, 127, 79, 0.5), or #367f4f80 in eight-digit hex. Over white that composites to #9BBFA7; over black, #1B4028.

Is #367f4f a web-safe color?
