Color scale — 50 to 950

  • 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
Minimum size as text on white

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.

What each alpha value actually composites to. The top row is #263d2c 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.

#263d2c, answered

What color is #263d2c?

#263d2c is a deep soft green, closest to Dark Slate Gray (ΔE2000 10.6). It sits at 136° on the hue wheel with 23% saturation and 19% lightness, which reads as cool.

What is the RGB value of #263d2c?

rgb(38, 61, 44) — 38 red, 61 green and 44 blue out of 255, or 14.9% / 23.9% / 17.3% by channel.

What is #263d2c in HSL and HSV?

hsl(136, 23%, 19%) and hsv(136, 38%, 24%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #263d2c a light or a dark color?

It is a dark color. Relative luminance is 0.0393 and perceived brightness is 21%, so white text on it reaches 11.76:1.

Should I use black or white text on #263d2c?

White. It scores 11.76:1 against #263d2c, versus 1.79:1 for black — AAA at any size.

Is #263d2c accessible on a white background?

#263d2c on white scores 11.76:1, which clears AAA at every size.

What is the complementary color of #263d2c?

#3D2637 sits directly opposite on the wheel. Softer options are the split-complements #37263D and #3D262B, which give the same contrast with far less vibration.

What colors go well with #263d2c?

For interface work: #F6F9F7 as the surface, #CDE0D2 for borders, #588D66 for secondary text, #3F243F as an accent and #314F39 for hover and pressed states. For a palette, the analogous pair #2B3D26 and #263D37 stays calm, while #3D2637 is the loudest partner.

What is #263d2c in CMYK for printing?

cmyk(38%, 0%, 28%, 76%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #263d2c warm or cool?

Cool — it scores 63 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #283D26; nudged cooler, #253E35.

Which Tailwind color is closest to #263d2c?

The neutral family — its 500 step is #737373, ΔE2000 25.3 away. That is a visible difference, so define #263d2c as a custom token rather than reaching for the built-in.

How do I use #263d2c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#263d2c] or text-[#263d2c], 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 #263d2c with 50% opacity?

rgba(38, 61, 44, 0.5), or #263d2c80 in eight-digit hex. Over white that composites to #939E96; over black, #131F16.

Is #263d2c a web-safe color?

No. The nearest web-safe colour is #333333, ΔE2000 14.5 away. The palette only matters for legacy displays and some email clients now.
