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 #aad1df

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 #234D5D
Safe as a 1px border on white
No — use #4E9FBC

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.

#aad1df, answered

What color is #aad1df?

#aad1df is a light vivid cyan, closest to Light Blue (ΔE2000 1.8). It sits at 196° on the hue wheel with 45% saturation and 77% lightness, which reads as cool.

What is the RGB value of #aad1df?

rgb(170, 209, 223) — 170 red, 209 green and 223 blue out of 255, or 66.7% / 82% / 87.5% by channel.

What is #aad1df in HSL and HSV?

hsl(196, 45%, 77%) and hsv(196, 24%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aad1df a light or a dark color?

It is a light color. Relative luminance is 0.5947 and perceived brightness is 78%, so black text on it reaches 12.89:1.

Should I use black or white text on #aad1df?

Black. It scores 12.89:1 against #aad1df, versus 1.63:1 for white — AAA at any size.

Is #aad1df accessible on a white background?

#aad1df on white scores 1.63:1, which fails WCAG AA at every size. Darken it to #397F98 to reach 4.5:1, or #2A5D70 for 7:1.

What is the complementary color of #aad1df?

#DFB8AA sits directly opposite on the wheel. Softer options are the split-complements #DFAAB7 and #DFD3AA, which give the same contrast with far less vibration.

What colors go well with #aad1df?

For interface work: #F4F9FA as the surface, #C4DFE9 for borders, #4B869B for secondary text, #983634 as an accent and #234D5D for hover and pressed states. For a palette, the analogous pair #AADFD3 and #AAB7DF stays calm, while #DFB8AA is the loudest partner.

What is #aad1df in CMYK for printing?

cmyk(24%, 6%, 0%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #aad1df warm or cool?

Cool — it scores 94 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AADFDA; nudged cooler, #A9C6E0.

Which Tailwind color is closest to #aad1df?

The cyan family — its 500 step is #06b6d4, ΔE2000 14.7 away. That is a visible difference, so define #aad1df as a custom token rather than reaching for the built-in.

How do I use #aad1df in Tailwind CSS?

Inline it as an arbitrary value with bg-[#aad1df] or text-[#aad1df], 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 #aad1df with 50% opacity?

rgba(170, 209, 223, 0.5), or #aad1df80 in eight-digit hex. Over white that composites to #D5E8EF; over black, #556970.

Is #aad1df a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 7.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #aad1df 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 #aad1df?

The safest is same-hue elevation: linear-gradient(135deg, #D7E9F0, #aad1df 45%, #234D5D). For more colour, a short hue run to #9594D7 keeps it rich without turning muddy.
