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 #d1eeeb

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
  • 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 #225D57
Safe as a 1px border on white
No — use #3CA298

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.

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

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

Transparency

What each alpha value actually composites to. The top row is #d1eeeb 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.

#d1eeeb, answered

What color is #d1eeeb?

#d1eeeb is a pale vivid cyan, closest to Light Cyan (ΔE2000 3.8). It sits at 174° on the hue wheel with 46% saturation and 88% lightness, which reads as cool.

What is the RGB value of #d1eeeb?

rgb(209, 238, 235) — 209 red, 238 green and 235 blue out of 255, or 82% / 93.3% / 92.2% by channel.

What is #d1eeeb in HSL and HSV?

hsl(174, 46%, 88%) and hsv(174, 12%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #d1eeeb a light or a dark color?

It is a light color. Relative luminance is 0.8070 and perceived brightness is 90%, so black text on it reaches 17.14:1.

Should I use black or white text on #d1eeeb?

Black. It scores 17.14:1 against #d1eeeb, versus 1.23:1 for white — AAA at any size.

Is #d1eeeb accessible on a white background?

#d1eeeb on white scores 1.23:1, which fails WCAG AA at every size. Darken it to #308178 to reach 4.5:1, or #235F59 for 7:1.

What is the complementary color of #d1eeeb?

#EED1D4 sits directly opposite on the wheel. Softer options are the split-complements #EED1E2 and #EEDCD1, which give the same contrast with far less vibration.

What colors go well with #d1eeeb?

For interface work: #F4FAFA as the surface, #C3E9E5 for borders, #4B9B93 for secondary text, #983457 as an accent and #225D57 for hover and pressed states. For a palette, the analogous pair #D1EEDC and #D1E2EE stays calm, while #EED1D4 is the loudest partner.

What is #d1eeeb in CMYK for printing?

cmyk(12%, 0%, 1%, 7%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #d1eeeb warm or cool?

Cool — it scores 85 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D1EEE0; nudged cooler, #D0E7EF.

Which Tailwind color is closest to #d1eeeb?

The cyan family — its 500 step is #06b6d4, ΔE2000 22.7 away. That is a visible difference, so define #d1eeeb as a custom token rather than reaching for the built-in.

How do I use #d1eeeb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#d1eeeb] or text-[#d1eeeb], 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 #d1eeeb with 50% opacity?

rgba(209, 238, 235, 0.5), or #d1eeeb80 in eight-digit hex. Over white that composites to #E8F7F5; over black, #697776.

Is #d1eeeb a web-safe color?

No. The nearest web-safe colour is #CCFFFF, ΔE2000 5.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #d1eeeb mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #d1eeeb?

The safest is same-hue elevation: linear-gradient(135deg, #F0F9F9, #d1eeeb 45%, #225D57). For more colour, a short hue run to #BACAE6 keeps it rich without turning muddy.
