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 #abeaf5

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 #0E6372
Safe as a 1px border on white
No — use #16A1B9

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.

#abeaf5, answered

What color is #abeaf5?

#abeaf5 is a light electric cyan, closest to Powder Blue (ΔE2000 3.4). It sits at 189° on the hue wheel with 79% saturation and 82% lightness, which reads as cool.

What is the RGB value of #abeaf5?

rgb(171, 234, 245) — 171 red, 234 green and 245 blue out of 255, or 67.1% / 91.8% / 96.1% by channel.

What is #abeaf5 in HSL and HSV?

hsl(189, 79%, 82%) and hsv(189, 30%, 96%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #abeaf5 a light or a dark color?

It is a light color. Relative luminance is 0.7410 and perceived brightness is 86%, so black text on it reaches 15.82:1.

Should I use black or white text on #abeaf5?

Black. It scores 15.82:1 against #abeaf5, versus 1.33:1 for white — AAA at any size.

Is #abeaf5 accessible on a white background?

#abeaf5 on white scores 1.33:1, which fails WCAG AA at every size. Darken it to #128195 to reach 4.5:1, or #0D6170 for 7:1.

What is the complementary color of #abeaf5?

#F5B6AB sits directly opposite on the wheel. Softer options are the split-complements #F5ABC5 and #F5DBAB, which give the same contrast with far less vibration.

What colors go well with #abeaf5?

For interface work: #F4FAFA as the surface, #C0E6ED for borders, #4B8F9B for secondary text, #BB1123 as an accent and #0E6372 for hover and pressed states. For a palette, the analogous pair #ABF5DB and #ABC5F5 stays calm, while #F5B6AB is the loudest partner.

What is #abeaf5 in CMYK for printing?

cmyk(30%, 5%, 0%, 4%). 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 #abeaf5 warm or cool?

Cool — it scores 91 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #ABF5E5; nudged cooler, #AAD6F6.

Which Tailwind color is closest to #abeaf5?

The cyan family — its 500 step is #06b6d4, ΔE2000 16.6 away. That is a visible difference, so define #abeaf5 as a custom token rather than reaching for the built-in.

How do I use #abeaf5 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#abeaf5] or text-[#abeaf5], 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 #abeaf5 with 50% opacity?

rgba(171, 234, 245, 0.5), or #abeaf580 in eight-digit hex. Over white that composites to #D5F5FA; over black, #56757B.

Is #abeaf5 a web-safe color?

No. The nearest web-safe colour is #99FFFF, ΔE2000 8 away. The palette only matters for legacy displays and some email clients now.

What does the color #abeaf5 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 #abeaf5?

The safest is same-hue elevation: linear-gradient(135deg, #E2F8FC, #abeaf5 45%, #0E6372). For more colour, a short hue run to #909AF2 keeps it rich without turning muddy.
