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 #97d2da

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
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #21575E
Safe as a 1px border on white
No — use #3EA1AF

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 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 #97d2da 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.

#97d2da, answered

What color is #97d2da?

#97d2da is a light vivid cyan, closest to Powder Blue (ΔE2000 4.3). It sits at 187° on the hue wheel with 48% saturation and 72% lightness, which reads as cool.

What is the RGB value of #97d2da?

rgb(151, 210, 218) — 151 red, 210 green and 218 blue out of 255, or 59.2% / 82.4% / 85.5% by channel.

What is #97d2da in HSL and HSV?

hsl(187, 48%, 72%) and hsv(187, 31%, 85%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #97d2da a light or a dark color?

It is a light color. Relative luminance is 0.5773 and perceived brightness is 77%, so black text on it reaches 12.55:1.

Should I use black or white text on #97d2da?

Black. It scores 12.55:1 against #97d2da, versus 1.67:1 for white — AAA at any size.

Is #97d2da accessible on a white background?

#97d2da on white scores 1.67:1, which fails WCAG AA at every size. Darken it to #317E89 to reach 4.5:1, or #255F67 for 7:1.

What is the complementary color of #97d2da?

#DA9F97 sits directly opposite on the wheel. Softer options are the split-complements #DA97B1 and #DAC197, which give the same contrast with far less vibration.

What colors go well with #97d2da?

For interface work: #F4FAFA as the surface, #C3E5EA for borders, #4B919B for secondary text, #9B3140 as an accent and #21575E for hover and pressed states. For a palette, the analogous pair #97DAC1 and #97B1DA stays calm, while #DA9F97 is the loudest partner.

What is #97d2da in CMYK for printing?

cmyk(31%, 4%, 0%, 15%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #97d2da warm or cool?

Cool — it scores 91 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #97DACA; nudged cooler, #96BEDB.

Which Tailwind color is closest to #97d2da?

The cyan family — its 500 step is #06b6d4, ΔE2000 12.7 away. That is a visible difference, so define #97d2da as a custom token rather than reaching for the built-in.

How do I use #97d2da in Tailwind CSS?

Inline it as an arbitrary value with bg-[#97d2da] or text-[#97d2da], 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 #97d2da with 50% opacity?

rgba(151, 210, 218, 0.5), or #97d2da80 in eight-digit hex. Over white that composites to #CBE9ED; over black, #4C696D.

Is #97d2da a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 3.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #97d2da mean?
