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 #a4d2cf

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • White 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
Not as text
Safe as a fill behind white type
No — use #2A5552
Safe as a 1px border on white
No — use #50A19C

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 lightness keeps it airy and approachable.

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 #a4d2cf 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.

#a4d2cf, answered

What color is #a4d2cf?

#a4d2cf is a light soft cyan, closest to Powder Blue (ΔE2000 5.1). It sits at 176° on the hue wheel with 34% saturation and 73% lightness, which reads as cool.

What is the RGB value of #a4d2cf?

rgb(164, 210, 207) — 164 red, 210 green and 207 blue out of 255, or 64.3% / 82.4% / 81.2% by channel.

What is #a4d2cf in HSL and HSV?

hsl(176, 34%, 73%) and hsv(176, 22%, 82%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a4d2cf a light or a dark color?

It is a light color. Relative luminance is 0.5849 and perceived brightness is 77%, so black text on it reaches 12.70:1.

Should I use black or white text on #a4d2cf?

Black. It scores 12.70:1 against #a4d2cf, versus 1.65:1 for white — AAA at any size.

Is #a4d2cf accessible on a white background?

#a4d2cf on white scores 1.65:1, which fails WCAG AA at every size. Darken it to #3F7F7B to reach 4.5:1, or #30615D for 7:1.

What is the complementary color of #a4d2cf?

#D2A4A7 sits directly opposite on the wheel. Softer options are the split-complements #D2A4BE and #D2B8A4, which give the same contrast with far less vibration.

What colors go well with #a4d2cf?

For interface work: #F5FAFA as the surface, #C8E4E2 for borders, #4C9A94 for secondary text, #8D3F57 as an accent and #2A5552 for hover and pressed states. For a palette, the analogous pair #A4D2B8 and #A4BED2 stays calm, while #D2A4A7 is the loudest partner.

What is #a4d2cf in CMYK for printing?

cmyk(22%, 0%, 1%, 18%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a4d2cf warm or cool?

Cool — it scores 85 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A4D2BE; nudged cooler, #A3C5D3.

Which Tailwind color is closest to #a4d2cf?

The teal family — its 500 step is #14b8a6, ΔE2000 15.8 away. That is a visible difference, so define #a4d2cf as a custom token rather than reaching for the built-in.

How do I use #a4d2cf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a4d2cf] or text-[#a4d2cf], 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 #a4d2cf with 50% opacity?

rgba(164, 210, 207, 0.5), or #a4d2cf80 in eight-digit hex. Over white that composites to #D2E9E7; over black, #526968.

Is #a4d2cf a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 2.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #a4d2cf mean?
