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 #ddf1fa

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 #10526F
Safe as a 1px border on white
No — use #209ED7

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.

#ddf1fa, answered

What color is #ddf1fa?

#ddf1fa is a pale vivid cyan, closest to Alice Blue (ΔE2000 4.8). It sits at 199° on the hue wheel with 74% saturation and 92% lightness, which reads as cool.

What is the RGB value of #ddf1fa?

rgb(221, 241, 250) — 221 red, 241 green and 250 blue out of 255, or 86.7% / 94.5% / 98% by channel.

What is #ddf1fa in HSL and HSV?

hsl(199, 74%, 92%) and hsv(199, 12%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ddf1fa a light or a dark color?

It is a light color. Relative luminance is 0.8518 and perceived brightness is 93%, so black text on it reaches 18.04:1.

Should I use black or white text on #ddf1fa?

Black. It scores 18.04:1 against #ddf1fa, versus 1.16:1 for white — AAA at any size.

Is #ddf1fa accessible on a white background?

#ddf1fa on white scores 1.16:1, which fails WCAG AA at every size. Darken it to #197EAB to reach 4.5:1, or #135D7E for 7:1.

What is the complementary color of #ddf1fa?

#FAE6DD sits directly opposite on the wheel. Softer options are the split-complements #FADDE3 and #FAF5DD, which give the same contrast with far less vibration.

What colors go well with #ddf1fa?

For interface work: #F4F9FA as the surface, #C0DFED for borders, #4B829B for secondary text, #B71F15 as an accent and #10526F for hover and pressed states. For a palette, the analogous pair #DDFAF5 and #DDE3FA stays calm, while #FAE6DD is the loudest partner.

What is #ddf1fa in CMYK for printing?

cmyk(12%, 4%, 0%, 2%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #ddf1fa warm or cool?

Cool — it scores 95 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DDFAF8; nudged cooler, #DDECFA.

Which Tailwind color is closest to #ddf1fa?

The cyan family — its 500 step is #06b6d4, ΔE2000 23.6 away. That is a visible difference, so define #ddf1fa as a custom token rather than reaching for the built-in.

How do I use #ddf1fa in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ddf1fa] or text-[#ddf1fa], 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 #ddf1fa with 50% opacity?

rgba(221, 241, 250, 0.5), or #ddf1fa80 in eight-digit hex. Over white that composites to #EEF8FD; over black, #6F797D.

Is #ddf1fa a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 10.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #ddf1fa 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 #ddf1fa?

The safest is same-hue elevation: linear-gradient(135deg, #EDF8FC, #ddf1fa 45%, #10526F). For more colour, a short hue run to #C6C3F6 keeps it rich without turning muddy.
