  • 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.

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.

#596c2b, answered

What color is #596c2b?

#596c2b is a dark soft green, closest to Dark Olive Green (ΔE2000 1.6). It sits at 78° on the hue wheel with 43% saturation and 30% lightness, which reads as warm.

What is the RGB value of #596c2b?

rgb(89, 108, 43) — 89 red, 108 green and 43 blue out of 255, or 34.9% / 42.4% / 16.9% by channel.

What is #596c2b in HSL and HSV?

hsl(78, 43%, 30%) and hsv(78, 60%, 42%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #596c2b a light or a dark color?

It is a dark color. Relative luminance is 0.1302 and perceived brightness is 38%, so white text on it reaches 5.83:1.

Should I use black or white text on #596c2b?

White. It scores 5.83:1 against #596c2b, versus 3.60:1 for black — AA at any size.

Is #596c2b accessible on a white background?

#596c2b on white scores 5.83:1, which clears AA at every size but not AAA.

What is the complementary color of #596c2b?

#3E2B6C sits directly opposite on the wheel. Softer options are the split-complements #2B396C and #5E2B6C, which give the same contrast with far less vibration.

What colors go well with #596c2b?

For interface work: #F9FAF4 as the surface, #DEE8C5 for borders, #839B4B for secondary text, #2B286F as an accent and #4B5B24 for hover and pressed states. For a palette, the analogous pair #6C5E2B and #396C2B stays calm, while #3E2B6C is the loudest partner.

What is #596c2b in CMYK for printing?

cmyk(18%, 0%, 60%, 58%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #596c2b warm or cool?

Warm — it scores 40 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #6C672B; nudged cooler, #416D2A.

Which Tailwind color is closest to #596c2b?

The neutral family — its 500 step is #737373, ΔE2000 22 away. That is a visible difference, so define #596c2b as a custom token rather than reaching for the built-in.

How do I use #596c2b in Tailwind CSS?

Inline it as an arbitrary value with bg-[#596c2b] or text-[#596c2b], 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 #596c2b with 50% opacity?

rgba(89, 108, 43, 0.5), or #596c2b80 in eight-digit hex. Over white that composites to #ACB695; over black, #2D3616.

Is #596c2b a web-safe color?

No. The nearest web-safe colour is #666633, ΔE2000 6.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #596c2b mean?
