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 #daf2f1

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 #215E5C
Safe as a 1px border on white
No — use #39A39F

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 high lightness makes it recede — a surface colour rather than a statement.

Worth knowing

At high lightness it disappears into white surfaces and thin strokes vanish entirely.

What each alpha value actually composites to. The top row is #daf2f1 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.

#daf2f1, answered

What color is #daf2f1?

#daf2f1 is a pale vivid cyan, closest to Light Cyan (ΔE2000 3.1). It sits at 178° on the hue wheel with 48% saturation and 90% lightness, which reads as cool.

What is the RGB value of #daf2f1?

rgb(218, 242, 241) — 218 red, 242 green and 241 blue out of 255, or 85.5% / 94.9% / 94.5% by channel.

What is #daf2f1 in HSL and HSV?

hsl(178, 48%, 90%) and hsv(178, 10%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #daf2f1 a light or a dark color?

It is a light color. Relative luminance is 0.8476 and perceived brightness is 92%, so black text on it reaches 17.95:1.

Should I use black or white text on #daf2f1?

Black. It scores 17.95:1 against #daf2f1, versus 1.17:1 for white — AAA at any size.

Is #daf2f1 accessible on a white background?

#daf2f1 on white scores 1.17:1, which fails WCAG AA at every size. Darken it to #2D817E to reach 4.5:1, or #215F5D for 7:1.

What is the complementary color of #daf2f1?

#F2DADB sits directly opposite on the wheel. Softer options are the split-complements #F2DAE7 and #F2E5DA, which give the same contrast with far less vibration.

What colors go well with #daf2f1?

For interface work: #F4FAFA as the surface, #C3EAE8 for borders, #4B9B98 for secondary text, #9B3152 as an accent and #215E5C for hover and pressed states. For a palette, the analogous pair #DAF2E5 and #DAE7F2 stays calm, while #F2DADB is the loudest partner.

What is #daf2f1 in CMYK for printing?

cmyk(10%, 0%, 0%, 5%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #daf2f1 warm or cool?

Cool — it scores 86 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DAF2E8; nudged cooler, #DAEAF3.

Which Tailwind color is closest to #daf2f1?

The cyan family — its 500 step is #06b6d4, ΔE2000 23.8 away. That is a visible difference, so define #daf2f1 as a custom token rather than reaching for the built-in.

How do I use #daf2f1 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#daf2f1] or text-[#daf2f1], 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 #daf2f1 with 50% opacity?

rgba(218, 242, 241, 0.5), or #daf2f180 in eight-digit hex. Over white that composites to #EDF9F8; over black, #6D7979.

Is #daf2f1 a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 6.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #daf2f1 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 #daf2f1?
