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 #8acacb

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #275858
Safe as a 1px border on white
No — use #48A1A2

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The lightness keeps it airy and approachable.

Worth knowing

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

Transparency

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.

#8acacb, answered

What color is #8acacb?

#8acacb is a light soft cyan, closest to Powder Blue (ΔE2000 7.4). It sits at 181° on the hue wheel with 39% saturation and 67% lightness, which reads as cool.

What is the RGB value of #8acacb?

rgb(138, 202, 203) — 138 red, 202 green and 203 blue out of 255, or 54.1% / 79.2% / 79.6% by channel.

What is #8acacb in HSL and HSV?

hsl(181, 39%, 67%) and hsv(181, 32%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8acacb a light or a dark color?

It is a light color. Relative luminance is 0.5196 and perceived brightness is 73%, so black text on it reaches 11.39:1.

Should I use black or white text on #8acacb?

Black. It scores 11.39:1 against #8acacb, versus 1.84:1 for white — AAA at any size.

Is #8acacb accessible on a white background?

#8acacb on white scores 1.84:1, which fails WCAG AA at every size. Darken it to #3A8182 to reach 4.5:1, or #2A5E5F for 7:1.

What is the complementary color of #8acacb?

#CB8B8A sits directly opposite on the wheel. Softer options are the split-complements #CB8AAA and #CBAC8A, which give the same contrast with far less vibration.

What colors go well with #8acacb?

For interface work: #F4FAFA as the surface, #C6E5E6 for borders, #4B9A9B for secondary text, #913B50 as an accent and #275858 for hover and pressed states. For a palette, the analogous pair #8ACBAC and #8AAACB stays calm, while #CB8B8A is the loudest partner.

What is #8acacb in CMYK for printing?

cmyk(32%, 1%, 0%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #8acacb warm or cool?

Cool — it scores 88 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8ACBB4; nudged cooler, #88B3CD.

Which Tailwind color is closest to #8acacb?

The cyan family — its 500 step is #06b6d4, ΔE2000 12.4 away. That is a visible difference, so define #8acacb as a custom token rather than reaching for the built-in.

How do I use #8acacb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8acacb] or text-[#8acacb], 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 #8acacb with 50% opacity?

rgba(138, 202, 203, 0.5), or #8acacb80 in eight-digit hex. Over white that composites to #C5E5E5; over black, #456566.

Is #8acacb a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 2.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #8acacb mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this moderate chroma the association is present but not shouted.

What gradient works with #8acacb?

The safest is same-hue elevation: linear-gradient(135deg, #B4DDDE, #8acacb 45%, #275858). For more colour, a short hue run to #7587C2 keeps it rich without turning muddy.
