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 #84acac

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #334C4C
Safe as a 1px border on white
No — use #6C9C9C

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 mid lightness keeps it versatile in both themes.

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.

#84acac, answered

What color is #84acac?

#84acac is a balanced soft cyan, closest to Cadet Blue (ΔE2000 6.9). It sits at 180° on the hue wheel with 19% saturation and 60% lightness, which reads as cool.

What is the RGB value of #84acac?

rgb(132, 172, 172) — 132 red, 172 green and 172 blue out of 255, or 51.8% / 67.5% / 67.5% by channel.

What is #84acac in HSL and HSV?

hsl(180, 19%, 60%) and hsv(180, 23%, 67%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #84acac a light or a dark color?

It is a mid-tone. Relative luminance is 0.3739 and perceived brightness is 63%, so black text on it reaches 8.48:1.

Should I use black or white text on #84acac?

Black. It scores 8.48:1 against #84acac, versus 2.48:1 for white — AAA at any size.

Is #84acac accessible on a white background?

#84acac on white scores 2.48:1, which fails WCAG AA at every size. Darken it to #537C7C to reach 4.5:1, or #3F5D5D for 7:1.

What is the complementary color of #84acac?

#AC8484 sits directly opposite on the wheel. Softer options are the split-complements #AC8498 and #AC9884, which give the same contrast with far less vibration.

What colors go well with #84acac?

For interface work: #F6F9F9 as the surface, #CEDEDE for borders, #5C8989 for secondary text, #B0808C as an accent and #334C4C for hover and pressed states. For a palette, the analogous pair #84AC98 and #8498AC stays calm, while #AC8484 is the loudest partner.

What is #84acac in CMYK for printing?

cmyk(23%, 0%, 0%, 33%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #84acac warm or cool?

Cool — it scores 71 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #84AC9D; nudged cooler, #829EAE.

Which Tailwind color is closest to #84acac?

The cyan family — its 500 step is #06b6d4, ΔE2000 12.9 away. That is a visible difference, so define #84acac as a custom token rather than reaching for the built-in.

How do I use #84acac in Tailwind CSS?

Inline it as an arbitrary value with bg-[#84acac] or text-[#84acac], 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 #84acac with 50% opacity?

rgba(132, 172, 172, 0.5), or #84acac80 in eight-digit hex. Over white that composites to #C2D6D6; over black, #425656.

Is #84acac a web-safe color?

No. The nearest web-safe colour is #999999, ΔE2000 14.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #84acac 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 #84acac?

The safest is same-hue elevation: linear-gradient(135deg, #A9C5C5, #84acac 45%, #334C4C). For more colour, a short hue run to #727DA0 keeps it rich without turning muddy.
