Works well for
  • Body text and links on white
  • Borders, dividers and quiet backgrounds
  • Long-form reading surfaces
  • Headers, footers and dark-mode surfaces
  • 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
Minimum size as text on white

Safe as a fill behind white type

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.

#53675b, answered

What color is #53675b?

#53675b is a dark muted green, closest to Dark Slate Gray (ΔE2000 10.9). It sits at 144° on the hue wheel with 11% saturation and 37% lightness, which reads as neutral.

What is the RGB value of #53675b?

rgb(83, 103, 91) — 83 red, 103 green and 91 blue out of 255, or 32.5% / 40.4% / 35.7% by channel.

What is #53675b in HSL and HSV?

hsl(144, 11%, 37%) and hsv(144, 19%, 40%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #53675b a light or a dark color?

It is a dark color. Relative luminance is 0.1229 and perceived brightness is 38%, so white text on it reaches 6.07:1.

Should I use black or white text on #53675b?

White. It scores 6.07:1 against #53675b, versus 3.46:1 for black — AA at any size.

Is #53675b accessible on a white background?

#53675b on white scores 6.07:1, which clears AA at every size but not AAA.

What is the complementary color of #53675b?

#67535F sits directly opposite on the wheel. Softer options are the split-complements #655367 and #675355, which give the same contrast with far less vibration.

What colors go well with #53675b?

For interface work: #F7F8F7 as the surface, #D2DBD5 for borders, #667F70 for secondary text, #6B4F67 as an accent and #39473E for hover and pressed states. For a palette, the analogous pair #556753 and #536765 stays calm, while #67535F is the loudest partner.

What is #53675b in CMYK for printing?

cmyk(19%, 0%, 12%, 60%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #53675b warm or cool?

Neutral — it scores 57 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #536754; nudged cooler, #516963.

Which Tailwind color is closest to #53675b?

The neutral family — its 500 step is #737373, ΔE2000 13.3 away. That is a visible difference, so define #53675b as a custom token rather than reaching for the built-in.

How do I use #53675b in Tailwind CSS?

Inline it as an arbitrary value with bg-[#53675b] or text-[#53675b], 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 #53675b with 50% opacity?

rgba(83, 103, 91, 0.5), or #53675b80 in eight-digit hex. Over white that composites to #A9B3AD; over black, #2A342E.

Is #53675b a web-safe color?
