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
  • Thin strokes and 1px borders — they disappear on light UI
  • 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.

cleantechnicalfreshclinical

Cyan reads as water, air and infrastructure: cool, hygienic, engineered.

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

At high lightness it disappears into white surfaces and thin strokes vanish entirely.

Transparency

What each alpha value actually composites to. The top row is #112921 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.

#112921, answered

What color is #112921?

#112921 is a deep soft cyan, closest to Dark Slate Gray (ΔE2000 12.9). It sits at 160° on the hue wheel with 41% saturation and 11% lightness, which reads as cool.

What is the RGB value of #112921?

rgb(17, 41, 33) — 17 red, 41 green and 33 blue out of 255, or 6.7% / 16.1% / 12.9% by channel.

What is #112921 in HSL and HSV?

hsl(160, 41%, 11%) and hsv(160, 59%, 16%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #112921 a light or a dark color?

It is a dark color. Relative luminance is 0.0181 and perceived brightness is 14%, so white text on it reaches 15.41:1.

Should I use black or white text on #112921?

White. It scores 15.41:1 against #112921, versus 1.36:1 for black — AAA at any size.

Is #112921 accessible on a white background?

#112921 on white scores 15.41:1, which clears AAA at every size.

What is the complementary color of #112921?

#291119 sits directly opposite on the wheel. Softer options are the split-complements #291125 and #291511, which give the same contrast with far less vibration.

What colors go well with #112921?

For interface work: #F4FAF8 as the surface, #C5E7DC for borders, #4B9B80 for secondary text, #2A101F as an accent and #255A49 for hover and pressed states. For a palette, the analogous pair #112915 and #112529 stays calm, while #291119 is the loudest partner.

What is #112921 in CMYK for printing?

cmyk(59%, 0%, 20%, 84%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #112921 warm or cool?

Cool — it scores 79 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #112918; nudged cooler, #10292A.

Which Tailwind color is closest to #112921?

The neutral family — its 500 step is #737373, ΔE2000 29.6 away. That is a visible difference, so define #112921 as a custom token rather than reaching for the built-in.

How do I use #112921 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#112921] or text-[#112921], 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 #112921 with 50% opacity?

rgba(17, 41, 33, 0.5), or #11292180 in eight-digit hex. Over white that composites to #889490; over black, #091511.

Is #112921 a web-safe color?
