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 #ade1ed

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 #175969
Safe as a 1px border on white
No — use #2AA2BE

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 lightness keeps it airy and approachable.

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 #ade1ed 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.

#ade1ed, answered

What color is #ade1ed?

#ade1ed is a light vivid cyan, closest to Powder Blue (ΔE2000 2.3). It sits at 191° on the hue wheel with 64% saturation and 80% lightness, which reads as cool.

What is the RGB value of #ade1ed?

rgb(173, 225, 237) — 173 red, 225 green and 237 blue out of 255, or 67.8% / 88.2% / 92.9% by channel.

What is #ade1ed in HSL and HSV?

hsl(191, 64%, 80%) and hsv(191, 27%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ade1ed a light or a dark color?

It is a light color. Relative luminance is 0.6885 and perceived brightness is 83%, so black text on it reaches 14.77:1.

Should I use black or white text on #ade1ed?

Black. It scores 14.77:1 against #ade1ed, versus 1.42:1 for white — AAA at any size.

Is #ade1ed accessible on a white background?

#ade1ed on white scores 1.42:1, which fails WCAG AA at every size. Darken it to #207E94 to reach 4.5:1, or #185E6E for 7:1.

What is the complementary color of #ade1ed?

#EDB9AD sits directly opposite on the wheel. Softer options are the split-complements #EDADC1 and #EDD9AD, which give the same contrast with far less vibration.

What colors go well with #ade1ed?

For interface work: #F4F9FA as the surface, #C0E4ED for borders, #4B8C9B for secondary text, #AB2129 as an accent and #175969 for hover and pressed states. For a palette, the analogous pair #ADEDD9 and #ADC1ED stays calm, while #EDB9AD is the loudest partner.

What is #ade1ed in CMYK for printing?

cmyk(27%, 5%, 0%, 7%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #ade1ed warm or cool?

Cool — it scores 92 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #ADEDE2; nudged cooler, #ACD1EE.

Which Tailwind color is closest to #ade1ed?

The cyan family — its 500 step is #06b6d4, ΔE2000 15.8 away. That is a visible difference, so define #ade1ed as a custom token rather than reaching for the built-in.

How do I use #ade1ed in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ade1ed] or text-[#ade1ed], 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 #ade1ed with 50% opacity?

rgba(173, 225, 237, 0.5), or #ade1ed80 in eight-digit hex. Over white that composites to #D6F0F6; over black, #577177.

Is #ade1ed a web-safe color?

No. The nearest web-safe colour is #99CCFF, ΔE2000 13.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #ade1ed 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 #ade1ed?

The safest is same-hue elevation: linear-gradient(135deg, #DFF3F8, #ade1ed 45%, #175969). For more colour, a short hue run to #9499E7 keeps it rich without turning muddy.
