How to use #0c7f7b

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
  • 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

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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 #0c7f7b 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.

#0c7f7b, answered

What color is #0c7f7b?

#0c7f7b is a dark electric cyan, closest to Teal (ΔE2000 1.7). It sits at 178° on the hue wheel with 83% saturation and 27% lightness, which reads as cool.

What is the RGB value of #0c7f7b?

rgb(12, 127, 123) — 12 red, 127 green and 123 blue out of 255, or 4.7% / 49.8% / 48.2% by channel.

What is #0c7f7b in HSL and HSV?

hsl(178, 83%, 27%) and hsv(178, 91%, 50%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #0c7f7b a light or a dark color?

It is a dark color. Relative luminance is 0.1669 and perceived brightness is 42%, so white text on it reaches 4.84:1.

Should I use black or white text on #0c7f7b?

White. It scores 4.84:1 against #0c7f7b, versus 4.34:1 for black — AA at any size.

Is #0c7f7b accessible on a white background?

#0c7f7b on white scores 4.84:1, which clears AA at every size but not AAA.

What is the complementary color of #0c7f7b?

#7F0C10 sits directly opposite on the wheel. Softer options are the split-complements #7F0C4A and #7F420C, which give the same contrast with far less vibration.

What colors go well with #0c7f7b?

For interface work: #F4FAFA as the surface, #C0EDEB for borders, #4B9B98 for secondary text, #82092C as an accent and #0B7471 for hover and pressed states. For a palette, the analogous pair #0C7F42 and #0C4A7F stays calm, while #7F0C10 is the loudest partner.

What is #0c7f7b in CMYK for printing?

cmyk(91%, 0%, 3%, 50%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #0c7f7b warm or cool?

Cool — it scores 87 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #0C7F51; nudged cooler, #0B5B81.

Which Tailwind color is closest to #0c7f7b?

The teal family — its 500 step is #14b8a6, ΔE2000 18.8 away. That is a visible difference, so define #0c7f7b as a custom token rather than reaching for the built-in.

How do I use #0c7f7b in Tailwind CSS?

Inline it as an arbitrary value with bg-[#0c7f7b] or text-[#0c7f7b], 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 #0c7f7b with 50% opacity?

rgba(12, 127, 123, 0.5), or #0c7f7b80 in eight-digit hex. Over white that composites to #86BFBD; over black, #06403E.

Is #0c7f7b a web-safe color?

No. The nearest web-safe colour is #006666, ΔE2000 8.9 away. The palette only matters for legacy displays and some email clients now.
