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 #dadff8

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
  • 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 #14236B
Safe as a 1px border on white
No — use #7C8DE6

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

trustedcalmcompetentcorporate

The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed.

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

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

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.

#dadff8, answered

What color is #dadff8?

#dadff8 is a pale vivid blue, closest to Lavender (ΔE2000 3). It sits at 230° on the hue wheel with 68% saturation and 91% lightness, which reads as cool.

What is the RGB value of #dadff8?

rgb(218, 223, 248) — 218 red, 223 green and 248 blue out of 255, or 85.5% / 87.5% / 97.3% by channel.

What is #dadff8 in HSL and HSV?

hsl(230, 68%, 91%) and hsv(230, 12%, 97%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #dadff8 a light or a dark color?

It is a light color. Relative luminance is 0.7446 and perceived brightness is 88%, so black text on it reaches 15.89:1.

Should I use black or white text on #dadff8?

Black. It scores 15.89:1 against #dadff8, versus 1.32:1 for white — AAA at any size.

Is #dadff8 accessible on a white background?

#dadff8 on white scores 1.32:1, which fails WCAG AA at every size. Darken it to #556CDF to reach 4.5:1, or #2A47D7 for 7:1.

What is the complementary color of #dadff8?

#F8F3DA sits directly opposite on the wheel. Softer options are the split-complements #F8E4DA and #EEF8DA, which give the same contrast with far less vibration.

What colors go well with #dadff8?

For interface work: #F4F5FA as the surface, #C0C7ED for borders, #4B589B for secondary text, #B0741C as an accent and #14236B for hover and pressed states. For a palette, the analogous pair #DAEEF8 and #E4DAF8 stays calm, while #F8F3DA is the loudest partner.

What is #dadff8 in CMYK for printing?

cmyk(12%, 10%, 0%, 3%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #dadff8 warm or cool?

Cool — it scores 89 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #E0DAF8; nudged cooler, #DAE7F8.

Which Tailwind color is closest to #dadff8?

The cyan family — its 500 step is #06b6d4, ΔE2000 28.1 away. That is a visible difference, so define #dadff8 as a custom token rather than reaching for the built-in.

How do I use #dadff8 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#dadff8] or text-[#dadff8], 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 #dadff8 with 50% opacity?

rgba(218, 223, 248, 0.5), or #dadff880 in eight-digit hex. Over white that composites to #EDEFFC; over black, #6D707C.

Is #dadff8 a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 8.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #dadff8 mean?

As a blue, it reads trusted, calm, competent. The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #dadff8?

The safest is same-hue elevation: linear-gradient(135deg, #EEF0FC, #dadff8 45%, #14236B). For more colour, a short hue run to #DEC0F3 keeps it rich without turning muddy.
