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 #acbac0

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

Works well for
  • Text and icons on dark surfaces
  • Borders, dividers and quiet backgrounds
  • Long-form reading 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 #374348
Safe as a 1px border on white
No — use #8398A1

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.

With almost no chroma left, the family association is barely present; treat it as a neutral that happens to lean this way. The lightness keeps it airy and approachable.

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 #acbac0 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.

#acbac0, answered

What color is #acbac0?

#acbac0 is a light muted cyan, closest to Silver (ΔE2000 6.6). It sits at 198° on the hue wheel with 14% saturation and 71% lightness, which reads as cool.

What is the RGB value of #acbac0?

rgb(172, 186, 192) — 172 red, 186 green and 192 blue out of 255, or 67.5% / 72.9% / 75.3% by channel.

What is #acbac0 in HSL and HSV?

hsl(198, 14%, 71%) and hsv(198, 10%, 75%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #acbac0 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4769 and perceived brightness is 72%, so black text on it reaches 10.54:1.

Should I use black or white text on #acbac0?

Black. It scores 10.54:1 against #acbac0, versus 1.99:1 for white — AAA at any size.

Is #acbac0 accessible on a white background?

#acbac0 on white scores 1.99:1, which fails WCAG AA at every size. Darken it to #647A84 to reach 4.5:1, or #4A5A61 for 7:1.

What is the complementary color of #acbac0?

#C0B2AC sits directly opposite on the wheel. Softer options are the split-complements #C0ACB0 and #C0BCAC, which give the same contrast with far less vibration.

What colors go well with #acbac0?

For interface work: #F6F8F8 as the surface, #D1D8DC for borders, #637982 for secondary text, #785554 as an accent and #374348 for hover and pressed states. For a palette, the analogous pair #ACC0BC and #ACB0C0 stays calm, while #C0B2AC is the loudest partner.

What is #acbac0 in CMYK for printing?

cmyk(10%, 3%, 0%, 25%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #acbac0 warm or cool?

Cool — it scores 68 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #ACC0BF; nudged cooler, #ABB6C2.

Which Tailwind color is closest to #acbac0?

The cyan family — its 500 step is #06b6d4, ΔE2000 18 away. That is a visible difference, so define #acbac0 as a custom token rather than reaching for the built-in.

How do I use #acbac0 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#acbac0] or text-[#acbac0], 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 #acbac0 with 50% opacity?

rgba(172, 186, 192, 0.5), or #acbac080 in eight-digit hex. Over white that composites to #D6DDE0; over black, #565D60.

Is #acbac0 a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 11.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #acbac0 mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this low chroma the association is faint; it behaves more like a neutral.

What gradient works with #acbac0?

The safest is same-hue elevation: linear-gradient(135deg, #CFD7DA, #acbac0 45%, #374348). For more colour, a short hue run to #9C9BB3 keeps it rich without turning muddy.
