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 #08abdc

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
  • Headers, footers and dark-mode surfaces
  • 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
  • Black 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 #04607B
Safe as a 1px border on white
No — use #079FCD

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 low lightness adds weight and formality.

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.

#08abdc, answered

What color is #08abdc?

#08abdc is a dark electric cyan, closest to Deep Sky Blue (ΔE2000 6.4). It sits at 194° on the hue wheel with 93% saturation and 45% lightness, which reads as cool.

What is the RGB value of #08abdc?

rgb(8, 171, 220) — 8 red, 171 green and 220 blue out of 255, or 3.1% / 67.1% / 86.3% by channel.

What is #08abdc in HSL and HSV?

hsl(194, 93%, 45%) and hsv(194, 96%, 86%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #08abdc a light or a dark color?

It is a mid-tone. Relative luminance is 0.3434 and perceived brightness is 59%, so black text on it reaches 7.87:1.

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

Black. It scores 7.87:1 against #08abdc, versus 2.67:1 for white — AAA at any size.

Is #08abdc accessible on a white background?

#08abdc on white scores 2.67:1, which fails WCAG AA at every size. Darken it to #067DA1 to reach 4.5:1, or #045E7A for 7:1.

What is the complementary color of #08abdc?

#DC3908 sits directly opposite on the wheel. Softer options are the split-complements #DC0841 and #DCA308, which give the same contrast with far less vibration.

What colors go well with #08abdc?

For interface work: #F4F9FA as the surface, #C0E2ED for borders, #4B889B for secondary text, #E10307 as an accent and #04607B for hover and pressed states. For a palette, the analogous pair #08DCA3 and #0841DC stays calm, while #DC3908 is the loudest partner.

What is #08abdc in CMYK for printing?

cmyk(96%, 22%, 0%, 14%). 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 #08abdc warm or cool?

Cool — it scores 93 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #08DCBF; nudged cooler, #068DDE.

Which Tailwind color is closest to #08abdc?

The sky family — its 500 step is #0ea5e9, ΔE2000 5.5 away. That is a visible difference, so define #08abdc as a custom token rather than reaching for the built-in.

How do I use #08abdc in Tailwind CSS?

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

rgba(8, 171, 220, 0.5), or #08abdc80 in eight-digit hex. Over white that composites to #84D5EE; over black, #04566E.

Is #08abdc a web-safe color?

No. The nearest web-safe colour is #0099CC, ΔE2000 5.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #08abdc 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 #08abdc?

The safest is same-hue elevation: linear-gradient(135deg, #2AC8F7, #08abdc 45%, #04607B). For more colour, a short hue run to #070ABE keeps it rich without turning muddy.
