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 #d3e4eb

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
  • 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 #284A58
Safe as a 1px border on white
No — use #5F9DB6

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.

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

At high lightness it disappears into white surfaces and thin strokes vanish entirely.

What each alpha value actually composites to. The top row is #d3e4eb 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.

#d3e4eb, answered

What color is #d3e4eb?

#d3e4eb is a pale soft cyan, closest to Alice Blue (ΔE2000 5.9). It sits at 198° on the hue wheel with 38% saturation and 88% lightness, which reads as cool.

What is the RGB value of #d3e4eb?

rgb(211, 228, 235) — 211 red, 228 green and 235 blue out of 255, or 82.7% / 89.4% / 92.2% by channel.

What is #d3e4eb in HSL and HSV?

hsl(198, 38%, 88%) and hsv(198, 10%, 92%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #d3e4eb a light or a dark color?

It is a light color. Relative luminance is 0.7533 and perceived brightness is 88%, so black text on it reaches 16.07:1.

Should I use black or white text on #d3e4eb?

Black. It scores 16.07:1 against #d3e4eb, versus 1.31:1 for white — AAA at any size.

Is #d3e4eb accessible on a white background?

#d3e4eb on white scores 1.31:1, which fails WCAG AA at every size. Darken it to #447D95 to reach 4.5:1, or #325D6E for 7:1.

What is the complementary color of #d3e4eb?

#EBDAD3 sits directly opposite on the wheel. Softer options are the split-complements #EBD3D8 and #EBE6D3, which give the same contrast with far less vibration.

What colors go well with #d3e4eb?

For interface work: #F4F9FA as the surface, #C7DDE5 for borders, #4B839B for secondary text, #8F403D as an accent and #284A58 for hover and pressed states. For a palette, the analogous pair #D3EBE6 and #D3D8EB stays calm, while #EBDAD3 is the loudest partner.

What is #d3e4eb in CMYK for printing?

cmyk(10%, 3%, 0%, 8%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #d3e4eb 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 #D3EBE9; nudged cooler, #D3DFEC.

Which Tailwind color is closest to #d3e4eb?

The cyan family — its 500 step is #06b6d4, ΔE2000 22.3 away. That is a visible difference, so define #d3e4eb as a custom token rather than reaching for the built-in.

How do I use #d3e4eb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#d3e4eb] or text-[#d3e4eb], 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 #d3e4eb with 50% opacity?

rgba(211, 228, 235, 0.5), or #d3e4eb80 in eight-digit hex. Over white that composites to #E9F2F5; over black, #6A7276.

Is #d3e4eb a web-safe color?

No. The nearest web-safe colour is #CCCCFF, ΔE2000 17 away. The palette only matters for legacy displays and some email clients now.

What does the color #d3e4eb mean?
