Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

Color scale — 50 to 950

How to use #082c2e

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Body text and links on white
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text on black or near-black surfaces
  • Full-page backgrounds — tiring over long sessions
  • 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
Any size
Safe as a fill behind white type
Yes
Safe as a 1px border 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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The low lightness adds weight and formality.

Worth knowing

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

What each alpha value actually composites to. The top row is #082c2e 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.

#082c2e, answered

What color is #082c2e?

#082c2e is a deep vivid cyan, closest to Dark Slate Gray (ΔE2000 11.2). It sits at 183° on the hue wheel with 70% saturation and 11% lightness, which reads as cool.

What is the RGB value of #082c2e?

rgb(8, 44, 46) — 8 red, 44 green and 46 blue out of 255, or 3.1% / 17.3% / 18% by channel.

What is #082c2e in HSL and HSV?

hsl(183, 70%, 11%) and hsv(183, 83%, 18%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #082c2e a light or a dark color?

It is a dark color. Relative luminance is 0.0205 and perceived brightness is 15%, so white text on it reaches 14.89:1.

Should I use black or white text on #082c2e?

White. It scores 14.89:1 against #082c2e, versus 1.41:1 for black — AAA at any size.

Is #082c2e accessible on a white background?

#082c2e on white scores 14.89:1, which clears AAA at every size.

What is the complementary color of #082c2e?

#2E0A08 sits directly opposite on the wheel. Softer options are the split-complements #2E0819 and #2E1D08, which give the same contrast with far less vibration.

What colors go well with #082c2e?

For interface work: #F4FAFA as the surface, #C0EAED for borders, #4B979B for secondary text, #2F070F as an accent and #13686D for hover and pressed states. For a palette, the analogous pair #082E1D and #08192E stays calm, while #2E0A08 is the loudest partner.

What is #082c2e in CMYK for printing?

cmyk(83%, 4%, 0%, 82%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #082c2e warm or cool?

Cool — it scores 89 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #082E22; nudged cooler, #071E2F.

Which Tailwind color is closest to #082c2e?

The gray family — its 500 step is #6b7280, ΔE2000 28.7 away. That is a visible difference, so define #082c2e as a custom token rather than reaching for the built-in.

How do I use #082c2e in Tailwind CSS?

Inline it as an arbitrary value with bg-[#082c2e] or text-[#082c2e], 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 #082c2e with 50% opacity?

rgba(8, 44, 46, 0.5), or #082c2e80 in eight-digit hex. Over white that composites to #849697; over black, #041617.

Is #082c2e a web-safe color?

No. The nearest web-safe colour is #003333, ΔE2000 3.5 away. The palette only matters for legacy displays and some email clients now.
