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.

How to use #32adbb

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

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #1B5D65
Safe as a 1px border on white
No — use #2FA2AF

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 mid lightness keeps it versatile in both themes.

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 #32adbb 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.

#32adbb, answered

What color is #32adbb?

#32adbb is a balanced vivid cyan, closest to Cadet Blue (ΔE2000 7.1). It sits at 186° on the hue wheel with 58% saturation and 47% lightness, which reads as cool.

What is the RGB value of #32adbb?

rgb(50, 173, 187) — 50 red, 173 green and 187 blue out of 255, or 19.6% / 67.8% / 73.3% by channel.

What is #32adbb in HSL and HSV?

hsl(186, 58%, 47%) and hsv(186, 73%, 73%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #32adbb a light or a dark color?

It is a mid-tone. Relative luminance is 0.3415 and perceived brightness is 59%, so black text on it reaches 7.83:1.

Should I use black or white text on #32adbb?

Black. It scores 7.83:1 against #32adbb, versus 2.68:1 for white — AAA at any size.

Is #32adbb accessible on a white background?

#32adbb on white scores 2.68:1, which fails WCAG AA at every size. Darken it to #25808B to reach 4.5:1, or #1B5F67 for 7:1.

What is the complementary color of #32adbb?

#BB4032 sits directly opposite on the wheel. Softer options are the split-complements #BB3269 and #BB8532, which give the same contrast with far less vibration.

What colors go well with #32adbb?

For interface work: #F4FAFA as the surface, #C0E8ED for borders, #4B939B for secondary text, #C02D43 as an accent and #1B5D65 for hover and pressed states. For a palette, the analogous pair #32BB85 and #3269BB stays calm, while #BB4032 is the loudest partner.

What is #32adbb in CMYK for printing?

cmyk(73%, 8%, 0%, 27%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #32adbb warm or cool?

Cool — it scores 90 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #32BB97; nudged cooler, #308CBD.

Which Tailwind color is closest to #32adbb?

The cyan family — its 500 step is #06b6d4, ΔE2000 5.4 away. That is a visible difference, so define #32adbb as a custom token rather than reaching for the built-in.

How do I use #32adbb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#32adbb] or text-[#32adbb], 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 #32adbb with 50% opacity?

rgba(50, 173, 187, 0.5), or #32adbb80 in eight-digit hex. Over white that composites to #99D6DD; over black, #19575E.

Is #32adbb a web-safe color?

No. The nearest web-safe colour is #3399CC, ΔE2000 14 away. The palette only matters for legacy displays and some email clients now.

What does the color #32adbb mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #32adbb?

The safest is same-hue elevation: linear-gradient(135deg, #58C6D2, #32adbb 45%, #1B5D65). For more colour, a short hue run to #2C3DA3 keeps it rich without turning muddy.
