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 #dfeaf3

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 #23435D
Safe as a 1px border on white
No — use #659AC5

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.

#dfeaf3, answered

What color is #dfeaf3?

#dfeaf3 is a pale vivid blue, closest to Alice Blue (ΔE2000 3.3). It sits at 207° on the hue wheel with 46% saturation and 91% lightness, which reads as cool.

What is the RGB value of #dfeaf3?

rgb(223, 234, 243) — 223 red, 234 green and 243 blue out of 255, or 87.5% / 91.8% / 95.3% by channel.

What is #dfeaf3 in HSL and HSV?

hsl(207, 46%, 91%) and hsv(207, 8%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #dfeaf3 a light or a dark color?

It is a light color. Relative luminance is 0.8100 and perceived brightness is 91%, so black text on it reaches 17.20:1.

Should I use black or white text on #dfeaf3?

Black. It scores 17.20:1 against #dfeaf3, versus 1.22:1 for white — AAA at any size.

Is #dfeaf3 accessible on a white background?

#dfeaf3 on white scores 1.22:1, which fails WCAG AA at every size. Darken it to #3F79A8 to reach 4.5:1, or #305C80 for 7:1.

What is the complementary color of #dfeaf3?

#F3E8DF sits directly opposite on the wheel. Softer options are the split-complements #F3DFE0 and #F3F2DF, which give the same contrast with far less vibration.

What colors go well with #dfeaf3?

For interface work: #F4F8FA as the surface, #C4D8E9 for borders, #4B779B for secondary text, #994A33 as an accent and #23435D for hover and pressed states. For a palette, the analogous pair #DFF3F2 and #DFE0F3 stays calm, while #F3E8DF is the loudest partner.

What is #dfeaf3 in CMYK for printing?

cmyk(8%, 4%, 0%, 5%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #dfeaf3 warm or cool?

Cool — it scores 99 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DFE3F3; nudged cooler, #CCDCED.

Which Tailwind color is closest to #dfeaf3?

The cyan family — its 500 step is #06b6d4, ΔE2000 24.7 away. That is a visible difference, so define #dfeaf3 as a custom token rather than reaching for the built-in.

How do I use #dfeaf3 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#dfeaf3] or text-[#dfeaf3], 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 #dfeaf3 with 50% opacity?

rgba(223, 234, 243, 0.5), or #dfeaf380 in eight-digit hex. Over white that composites to #EFF5F9; over black, #70757A.

Is #dfeaf3 a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 13.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #dfeaf3 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 #dfeaf3?

The safest is same-hue elevation: linear-gradient(135deg, #F0F5F9, #dfeaf3 45%, #23435D). For more colour, a short hue run to #D0C9EB keeps it rich without turning muddy.
