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 #a8feee

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 #017E67
Safe as a 1px border on white
No — use #02A586

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The lightness keeps it airy and approachable.

Worth knowing

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

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.

#a8feee, answered

What color is #a8feee?

#a8feee is a light electric cyan, closest to Pale Turquoise (ΔE2000 7.3). It sits at 169° on the hue wheel with 98% saturation and 83% lightness, which reads as cool.

What is the RGB value of #a8feee?

rgb(168, 254, 238) — 168 red, 254 green and 238 blue out of 255, or 65.9% / 99.6% / 93.3% by channel.

What is #a8feee in HSL and HSV?

hsl(169, 98%, 83%) and hsv(169, 34%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a8feee a light or a dark color?

It is a light color. Relative luminance is 0.8538 and perceived brightness is 90%, so black text on it reaches 18.08:1.

Should I use black or white text on #a8feee?

Black. It scores 18.08:1 against #a8feee, versus 1.16:1 for white — AAA at any size.

Is #a8feee accessible on a white background?

#a8feee on white scores 1.16:1, which fails WCAG AA at every size. Darken it to #02826A to reach 4.5:1, or #016351 for 7:1.

What is the complementary color of #a8feee?

#FEA8B8 sits directly opposite on the wheel. Softer options are the split-complements #FEA8E3 and #FEC3A8, which give the same contrast with far less vibration.

What colors go well with #a8feee?

For interface work: #F4FAF9 as the surface, #C0EDE4 for borders, #4B9B8C for secondary text, #CC0058 as an accent and #017E67 for hover and pressed states. For a palette, the analogous pair #A8FEC3 and #A8E3FE stays calm, while #FEA8B8 is the loudest partner.

What is #a8feee in CMYK for printing?

cmyk(34%, 0%, 6%, 0%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #a8feee warm or cool?

Cool — it scores 83 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A8FECE; nudged cooler, #A7EFFF.

Which Tailwind color is closest to #a8feee?

The teal family — its 500 step is #14b8a6, ΔE2000 19 away. That is a visible difference, so define #a8feee as a custom token rather than reaching for the built-in.

How do I use #a8feee in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a8feee] or text-[#a8feee], 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 #a8feee with 50% opacity?

rgba(168, 254, 238, 0.5), or #a8feee80 in eight-digit hex. Over white that composites to #D4FFF7; over black, #547F77.

Is #a8feee a web-safe color?

No. The nearest web-safe colour is #99FFFF, ΔE2000 6 away. The palette only matters for legacy displays and some email clients now.

What does the color #a8feee 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 #a8feee?

The safest is same-hue elevation: linear-gradient(135deg, #E4FFFA, #a8feee 45%, #017E67). For more colour, a short hue run to #8ABCFE keeps it rich without turning muddy.
