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.

Color scale — 50 to 950

How to use #dadcef

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
  • 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 #272B59
Safe as a 1px border on white
No — use #888FCC

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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.

#dadcef, answered

What color is #dadcef?

#dadcef is a pale soft blue, closest to Lavender (ΔE2000 2.5). It sits at 234° on the hue wheel with 40% saturation and 90% lightness, which reads as cool.

What is the RGB value of #dadcef?

rgb(218, 220, 239) — 218 red, 220 green and 239 blue out of 255, or 85.5% / 86.3% / 93.7% by channel.

What is #dadcef in HSL and HSV?

hsl(234, 40%, 90%) and hsv(234, 9%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #dadcef a light or a dark color?

It is a light color. Relative luminance is 0.7232 and perceived brightness is 87%, so black text on it reaches 15.46:1.

Should I use black or white text on #dadcef?

Black. It scores 15.46:1 against #dadcef, versus 1.36:1 for white — AAA at any size.

Is #dadcef accessible on a white background?

#dadcef on white scores 1.36:1, which fails WCAG AA at every size. Darken it to #6870BE to reach 4.5:1, or #464FA2 for 7:1.

What is the complementary color of #dadcef?

#EFEDDA sits directly opposite on the wheel. Softer options are the split-complements #EFE2DA and #E6EFDA, which give the same contrast with far less vibration.

What colors go well with #dadcef?

For interface work: #F4F5FA as the surface, #C6C9E6 for borders, #4B529B for secondary text, #92733A as an accent and #272B59 for hover and pressed states. For a palette, the analogous pair #DAE6EF and #E2DAEF stays calm, while #EFEDDA is the loudest partner.

What is #dadcef in CMYK for printing?

cmyk(9%, 8%, 0%, 6%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #dadcef warm or cool?

Cool — it scores 87 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #E0DAEF; nudged cooler, #D9E3F0.

Which Tailwind color is closest to #dadcef?

The cyan family — its 500 step is #06b6d4, ΔE2000 29 away. That is a visible difference, so define #dadcef as a custom token rather than reaching for the built-in.

How do I use #dadcef in Tailwind CSS?

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

rgba(218, 220, 239, 0.5), or #dadcef80 in eight-digit hex. Over white that composites to #EDEEF7; over black, #6D6E78.

Is #dadcef a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 10 away. The palette only matters for legacy displays and some email clients now.

What does the color #dadcef 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 moderate chroma the association is present but not shouted.

What gradient works with #dadcef?

The safest is same-hue elevation: linear-gradient(135deg, #F1F2F9, #dadcef 45%, #272B59). For more colour, a short hue run to #DAC5E6 keeps it rich without turning muddy.
