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 #a6ebfc

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 #04647B
Safe as a 1px border on white
No — use #07A0C5

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.

What each alpha value actually composites to. The top row is #a6ebfc 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.

#a6ebfc, answered

What color is #a6ebfc?

#a6ebfc is a light electric cyan, closest to Powder Blue (ΔE2000 4.9). It sits at 192° on the hue wheel with 94% saturation and 82% lightness, which reads as cool.

What is the RGB value of #a6ebfc?

rgb(166, 235, 252) — 166 red, 235 green and 252 blue out of 255, or 65.1% / 92.2% / 98.8% by channel.

What is #a6ebfc in HSL and HSV?

hsl(192, 94%, 82%) and hsv(192, 34%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a6ebfc a light or a dark color?

It is a light color. Relative luminance is 0.7455 and perceived brightness is 86%, so black text on it reaches 15.91:1.

Should I use black or white text on #a6ebfc?

Black. It scores 15.91:1 against #a6ebfc, versus 1.32:1 for white — AAA at any size.

Is #a6ebfc accessible on a white background?

#a6ebfc on white scores 1.32:1, which fails WCAG AA at every size. Darken it to #05809E to reach 4.5:1, or #046076 for 7:1.

What is the complementary color of #a6ebfc?

#FCB7A6 sits directly opposite on the wheel. Softer options are the split-complements #FCA6C0 and #FCE2A6, which give the same contrast with far less vibration.

What colors go well with #a6ebfc?

For interface work: #F4F9FA as the surface, #C0E4ED for borders, #4B8B9B for secondary text, #CA020D as an accent and #04647B for hover and pressed states. For a palette, the analogous pair #A6FCE2 and #A6C0FC stays calm, while #FCB7A6 is the loudest partner.

What is #a6ebfc in CMYK for printing?

cmyk(34%, 7%, 0%, 1%). 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 #a6ebfc 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 #A6FCEE; nudged cooler, #A5D8FD.

Which Tailwind color is closest to #a6ebfc?

The cyan family — its 500 step is #06b6d4, ΔE2000 16 away. That is a visible difference, so define #a6ebfc as a custom token rather than reaching for the built-in.

How do I use #a6ebfc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a6ebfc] or text-[#a6ebfc], 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 #a6ebfc with 50% opacity?

rgba(166, 235, 252, 0.5), or #a6ebfc80 in eight-digit hex. Over white that composites to #D3F5FE; over black, #53767E.

Is #a6ebfc a web-safe color?

No. The nearest web-safe colour is #99FFFF, ΔE2000 9 away. The palette only matters for legacy displays and some email clients now.

What does the color #a6ebfc 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 #a6ebfc?

The safest is same-hue elevation: linear-gradient(135deg, #E1F8FE, #a6ebfc 45%, #04647B). For more colour, a short hue run to #898EFB keeps it rich without turning muddy.
