How to use #116552

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.

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.

Transparency

What each alpha value actually composites to. The top row is #116552 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.

#116552, answered

What color is #116552?

#116552 is a deep vivid cyan, closest to Teal (ΔE2000 12.8). It sits at 166° on the hue wheel with 71% saturation and 23% lightness, which reads as cool.

What is the RGB value of #116552?

rgb(17, 101, 82) — 17 red, 101 green and 82 blue out of 255, or 6.7% / 39.6% / 32.2% by channel.

What is #116552 in HSL and HSV?

hsl(166, 71%, 23%) and hsv(166, 83%, 40%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #116552 a light or a dark color?

It is a dark color. Relative luminance is 0.1004 and perceived brightness is 32%, so white text on it reaches 6.98:1.

Should I use black or white text on #116552?

White. It scores 6.98:1 against #116552, versus 3.01:1 for black — AA at any size.

Is #116552 accessible on a white background?

#116552 on white scores 6.98:1, which clears AA at every size but not AAA.

What is the complementary color of #116552?

#651124 sits directly opposite on the wheel. Softer options are the split-complements #65114E and #652811, which give the same contrast with far less vibration.

What colors go well with #116552?

For interface work: #F4FAF9 as the surface, #C0EDE2 for borders, #4B9B89 for secondary text, #670F39 as an accent and #126D59 for hover and pressed states. For a palette, the analogous pair #116528 and #114E65 stays calm, while #651124 is the loudest partner.

What is #116552 in CMYK for printing?

cmyk(83%, 0%, 19%, 60%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #116552 warm or cool?

Cool — it scores 82 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #116533; nudged cooler, #105A66.

Which Tailwind color is closest to #116552?

The neutral family — its 500 step is #737373, ΔE2000 23.5 away. That is a visible difference, so define #116552 as a custom token rather than reaching for the built-in.

How do I use #116552 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#116552] or text-[#116552], 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 #116552 with 50% opacity?

rgba(17, 101, 82, 0.5), or #11655280 in eight-digit hex. Over white that composites to #88B2A9; over black, #093329.

Is #116552 a web-safe color?

No. The nearest web-safe colour is #006666, ΔE2000 8.3 away. The palette only matters for legacy displays and some email clients now.
