  • Brand accents, badges and data highlights
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.

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.

What each alpha value actually composites to. The top row is #577261 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.

#577261, answered

What color is #577261?

#577261 is a dark muted green, closest to Dark Olive Green (ΔE2000 13.4). It sits at 142° on the hue wheel with 13% saturation and 39% lightness, which reads as cool.

What is the RGB value of #577261?

rgb(87, 114, 97) — 87 red, 114 green and 97 blue out of 255, or 34.1% / 44.7% / 38% by channel.

What is #577261 in HSL and HSV?

hsl(142, 13%, 39%) and hsv(142, 24%, 45%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #577261 a light or a dark color?

It is a dark color. Relative luminance is 0.1492 and perceived brightness is 41%, so white text on it reaches 5.27:1.

Should I use black or white text on #577261?

White. It scores 5.27:1 against #577261, versus 3.98:1 for black — AA at any size.

Is #577261 accessible on a white background?

#577261 on white scores 5.27:1, which clears AA at every size but not AAA.

What is the complementary color of #577261?

#725768 sits directly opposite on the wheel. Softer options are the split-complements #6E5772 and #72575B, which give the same contrast with far less vibration.

What colors go well with #577261?

For interface work: #F6F8F7 as the surface, #D1DCD5 for borders, #63826F for secondary text, #765372 as an accent and #37483E for hover and pressed states. For a palette, the analogous pair #5B7257 and #57726E stays calm, while #725768 is the loudest partner.

What is #577261 in CMYK for printing?

cmyk(24%, 0%, 15%, 55%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #577261 warm or cool?

Cool — it scores 58 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #577257; nudged cooler, #55746C.

Which Tailwind color is closest to #577261?

The neutral family — its 500 step is #737373, ΔE2000 14.7 away. That is a visible difference, so define #577261 as a custom token rather than reaching for the built-in.

How do I use #577261 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#577261] or text-[#577261], 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 #577261 with 50% opacity?

rgba(87, 114, 97, 0.5), or #57726180 in eight-digit hex. Over white that composites to #ABB9B0; over black, #2C3931.

Is #577261 a web-safe color?
