How to use #08ac83

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 #067A5D
Safe as a 1px border on white
No — use #08A77F

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.

Transparency

What each alpha value actually composites to. The top row is #08ac83 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.

#08ac83, answered

What color is #08ac83?

#08ac83 is a dark electric cyan, closest to Medium Sea Green (ΔE2000 6.8). It sits at 165° on the hue wheel with 91% saturation and 35% lightness, which reads as cool.

What is the RGB value of #08ac83?

rgb(8, 172, 131) — 8 red, 172 green and 131 blue out of 255, or 3.1% / 67.5% / 51.4% by channel.

What is #08ac83 in HSL and HSV?

hsl(165, 91%, 35%) and hsv(165, 95%, 67%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #08ac83 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3120 and perceived brightness is 55%, so black text on it reaches 7.24:1.

Should I use black or white text on #08ac83?

Black. It scores 7.24:1 against #08ac83, versus 2.90:1 for white — AAA at any size.

Is #08ac83 accessible on a white background?

#08ac83 on white scores 2.90:1, which fails WCAG AA at every size. Darken it to #068565 to reach 4.5:1, or #05634B for 7:1.

What is the complementary color of #08ac83?

#AC0831 sits directly opposite on the wheel. Softer options are the split-complements #AC0883 and #AC3108, which give the same contrast with far less vibration.

What colors go well with #08ac83?

For interface work: #F4FAF9 as the surface, #C0EDE1 for borders, #4B9B87 for secondary text, #B0045A as an accent and #067A5D for hover and pressed states. For a palette, the analogous pair #08AC31 and #0883AC stays calm, while #AC0831 is the loudest partner.

What is #08ac83 in CMYK for printing?

cmyk(95%, 0%, 24%, 33%). 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 #08ac83 warm or cool?

Cool — it scores 81 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #08AC47; nudged cooler, #069AAE.

Which Tailwind color is closest to #08ac83?

The emerald family — its 500 step is #10b981, ΔE2000 4.8 away. That is a visible difference, so define #08ac83 as a custom token rather than reaching for the built-in.

How do I use #08ac83 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#08ac83] or text-[#08ac83], 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 #08ac83 with 50% opacity?

rgba(8, 172, 131, 0.5), or #08ac8380 in eight-digit hex. Over white that composites to #84D6C1; over black, #045642.

Is #08ac83 a web-safe color?

No. The nearest web-safe colour is #009999, ΔE2000 14.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #08ac83 mean?
