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 #08afed

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #045B7B
Safe as a 1px border on white
No — use #079DD4

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 mid lightness keeps it versatile in both themes.

Worth knowing

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

Transparency

What each alpha value actually composites to. The top row is #08afed 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.

#08afed, answered

What color is #08afed?

#08afed is a balanced electric cyan, closest to Deep Sky Blue (ΔE2000 4.4). It sits at 196° on the hue wheel with 94% saturation and 48% lightness, which reads as cool.

What is the RGB value of #08afed?

rgb(8, 175, 237) — 8 red, 175 green and 237 blue out of 255, or 3.1% / 68.6% / 92.9% by channel.

What is #08afed in HSL and HSV?

hsl(196, 94%, 48%) and hsv(196, 97%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #08afed a light or a dark color?

It is a mid-tone. Relative luminance is 0.3683 and perceived brightness is 61%, so black text on it reaches 8.37:1.

Should I use black or white text on #08afed?

Black. It scores 8.37:1 against #08afed, versus 2.51:1 for white — AAA at any size.

Is #08afed accessible on a white background?

#08afed on white scores 2.51:1, which fails WCAG AA at every size. Darken it to #067CA8 to reach 4.5:1, or #045F80 for 7:1.

What is the complementary color of #08afed?

#ED4608 sits directly opposite on the wheel. Softer options are the split-complements #ED083D and #EDB808, which give the same contrast with far less vibration.

What colors go well with #08afed?

For interface work: #F4F9FA as the surface, #C0E1ED for borders, #4B859B for secondary text, #F20803 as an accent and #045B7B for hover and pressed states. For a palette, the analogous pair #08EDB8 and #083DED stays calm, while #ED4608 is the loudest partner.

What is #08afed in CMYK for printing?

cmyk(97%, 26%, 0%, 7%). 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 #08afed 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 #08EDD7; nudged cooler, #0695EF.

Which Tailwind color is closest to #08afed?

The sky family — its 500 step is #0ea5e9, ΔE2000 3.5 away. That is a visible difference, so define #08afed as a custom token rather than reaching for the built-in.

How do I use #08afed in Tailwind CSS?

Inline it as an arbitrary value with bg-[#08afed] or text-[#08afed], 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 #08afed with 50% opacity?

rgba(8, 175, 237, 0.5), or #08afed80 in eight-digit hex. Over white that composites to #84D7F6; over black, #045877.

Is #08afed a web-safe color?

No. The nearest web-safe colour is #0099FF, ΔE2000 10.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #08afed 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 #08afed?

The safest is same-hue elevation: linear-gradient(135deg, #3AC5F8, #08afed 45%, #045B7B). For more colour, a short hue run to #0B07CF keeps it rich without turning muddy.
