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 #aecad4

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 #2C4953
Safe as a 1px border on white
No — use #689CAF

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 lightness keeps it airy and approachable.

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 #aecad4 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.

#aecad4, answered

What color is #aecad4?

#aecad4 is a light soft cyan, closest to Light Blue (ΔE2000 4.6). It sits at 196° on the hue wheel with 31% saturation and 76% lightness, which reads as cool.

What is the RGB value of #aecad4?

rgb(174, 202, 212) — 174 red, 202 green and 212 blue out of 255, or 68.2% / 79.2% / 83.1% by channel.

What is #aecad4 in HSL and HSV?

hsl(196, 31%, 76%) and hsv(196, 18%, 83%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aecad4 a light or a dark color?

It is a light color. Relative luminance is 0.5599 and perceived brightness is 77%, so black text on it reaches 12.20:1.

Should I use black or white text on #aecad4?

Black. It scores 12.20:1 against #aecad4, versus 1.72:1 for white — AAA at any size.

Is #aecad4 accessible on a white background?

#aecad4 on white scores 1.72:1, which fails WCAG AA at every size. Darken it to #4C7D8E to reach 4.5:1, or #385D6A for 7:1.

What is the complementary color of #aecad4?

#D4B8AE sits directly opposite on the wheel. Softer options are the split-complements #D4AEB7 and #D4CBAE, which give the same contrast with far less vibration.

What colors go well with #aecad4?

For interface work: #F5F8FA as the surface, #CADCE3 for borders, #508396 for secondary text, #894343 as an accent and #2C4953 for hover and pressed states. For a palette, the analogous pair #AED4CB and #AEB7D4 stays calm, while #D4B8AE is the loudest partner.

What is #aecad4 in CMYK for printing?

cmyk(18%, 5%, 0%, 17%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #aecad4 warm or cool?

Cool — it scores 89 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AED4D0; nudged cooler, #ADC2D5.

Which Tailwind color is closest to #aecad4?

The cyan family — its 500 step is #06b6d4, ΔE2000 15.9 away. That is a visible difference, so define #aecad4 as a custom token rather than reaching for the built-in.

How do I use #aecad4 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#aecad4] or text-[#aecad4], 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 #aecad4 with 50% opacity?

rgba(174, 202, 212, 0.5), or #aecad480 in eight-digit hex. Over white that composites to #D7E5EA; over black, #57656A.

Is #aecad4 a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 8.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #aecad4 mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this moderate chroma the association is present but not shouted.

What gradient works with #aecad4?

The safest is same-hue elevation: linear-gradient(135deg, #D6E4E9, #aecad4 45%, #2C4953). For more colour, a short hue run to #9B9AC9 keeps it rich without turning muddy.
