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 #d4ecfc

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 #084B77
Safe as a 1px border on white
No — use #1A9AEF

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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.

What each alpha value actually composites to. The top row is #d4ecfc 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.

#d4ecfc, answered

What color is #d4ecfc?

#d4ecfc is a pale electric blue, closest to Alice Blue (ΔE2000 6.4). It sits at 204° on the hue wheel with 87% saturation and 91% lightness, which reads as cool.

What is the RGB value of #d4ecfc?

rgb(212, 236, 252) — 212 red, 236 green and 252 blue out of 255, or 83.1% / 92.5% / 98.8% by channel.

What is #d4ecfc in HSL and HSV?

hsl(204, 87%, 91%) and hsv(204, 16%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #d4ecfc a light or a dark color?

It is a light color. Relative luminance is 0.8102 and perceived brightness is 91%, so black text on it reaches 17.20:1.

Should I use black or white text on #d4ecfc?

Black. It scores 17.20:1 against #d4ecfc, versus 1.22:1 for white — AAA at any size.

Is #d4ecfc accessible on a white background?

#d4ecfc on white scores 1.22:1, which fails WCAG AA at every size. Darken it to #0E7BC4 to reach 4.5:1, or #0A5A8F for 7:1.

What is the complementary color of #d4ecfc?

#FCE4D4 sits directly opposite on the wheel. Softer options are the split-complements #FCD4D8 and #FCF8D4, which give the same contrast with far less vibration.

What colors go well with #d4ecfc?

For interface work: #F4F8FA as the surface, #C0DBED for borders, #4B7B9B for secondary text, #C32409 as an accent and #084B77 for hover and pressed states. For a palette, the analogous pair #D4FCF8 and #D4D8FC stays calm, while #FCE4D4 is the loudest partner.

What is #d4ecfc in CMYK for printing?

cmyk(16%, 6%, 0%, 1%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #d4ecfc warm or cool?

Cool — it scores 98 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D4FBFC; nudged cooler, #D4E8FC.

Which Tailwind color is closest to #d4ecfc?

The cyan family — its 500 step is #06b6d4, ΔE2000 22.1 away. That is a visible difference, so define #d4ecfc as a custom token rather than reaching for the built-in.

How do I use #d4ecfc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#d4ecfc] or text-[#d4ecfc], 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 #d4ecfc with 50% opacity?

rgba(212, 236, 252, 0.5), or #d4ecfc80 in eight-digit hex. Over white that composites to #EAF6FE; over black, #6A767E.

Is #d4ecfc a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 11.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #d4ecfc 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 #d4ecfc?
