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 #d3e4df

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 #314F46
Safe as a 1px border on white
No — use #65A08F

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 #d3e4df 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.

#d3e4df, answered

What color is #d3e4df?

#d3e4df is a pale soft cyan, closest to Azure (ΔE2000 6.4). It sits at 162° on the hue wheel with 24% saturation and 86% lightness, which reads as cool.

What is the RGB value of #d3e4df?

rgb(211, 228, 223) — 211 red, 228 green and 223 blue out of 255, or 82.7% / 89.4% / 87.5% by channel.

What is #d3e4df in HSL and HSV?

hsl(162, 24%, 86%) and hsv(162, 7%, 89%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #d3e4df a light or a dark color?

It is a light color. Relative luminance is 0.7466 and perceived brightness is 87%, so black text on it reaches 15.93:1.

Should I use black or white text on #d3e4df?

Black. It scores 15.93:1 against #d3e4df, versus 1.32:1 for white — AAA at any size.

Is #d3e4df accessible on a white background?

#d3e4df on white scores 1.32:1, which fails WCAG AA at every size. Darken it to #4E7F70 to reach 4.5:1, or #3A5F54 for 7:1.

What is the complementary color of #d3e4df?

#E4D3D8 sits directly opposite on the wheel. Softer options are the split-complements #E4D3E1 and #E4D7D3, which give the same contrast with far less vibration.

What colors go well with #d3e4df?

For interface work: #F6F9F8 as the surface, #CCE0DA for borders, #578E7E for secondary text, #814B67 as an accent and #314F46 for hover and pressed states. For a palette, the analogous pair #D3E4D7 and #D3E1E4 stays calm, while #E4D3D8 is the loudest partner.

What is #d3e4df in CMYK for printing?

cmyk(8%, 0%, 2%, 11%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #d3e4df warm or cool?

Cool — it scores 71 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D3E4D9; nudged cooler, #D2E3E5.

Which Tailwind color is closest to #d3e4df?

The cyan family — its 500 step is #06b6d4, ΔE2000 23.8 away. That is a visible difference, so define #d3e4df as a custom token rather than reaching for the built-in.

How do I use #d3e4df in Tailwind CSS?

Inline it as an arbitrary value with bg-[#d3e4df] or text-[#d3e4df], 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 #d3e4df with 50% opacity?

rgba(211, 228, 223, 0.5), or #d3e4df80 in eight-digit hex. Over white that composites to #E9F2EF; over black, #6A7270.

Is #d3e4df a web-safe color?

No. The nearest web-safe colour is #CCCCCC, ΔE2000 9.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #d3e4df mean?
