How to use #84a39b

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
  • Brand accents, badges and data highlights
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 #374944
Safe as a 1px border on white
No — use #789A91

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 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.

#84a39b, answered

What color is #84a39b?

#84a39b is a balanced muted cyan, closest to Cadet Blue (ΔE2000 8). It sits at 165° on the hue wheel with 14% saturation and 58% lightness, which reads as cool.

What is the RGB value of #84a39b?

rgb(132, 163, 155) — 132 red, 163 green and 155 blue out of 255, or 51.8% / 63.9% / 60.8% by channel.

What is #84a39b in HSL and HSV?

hsl(165, 14%, 58%) and hsv(165, 19%, 64%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #84a39b a light or a dark color?

It is a mid-tone. Relative luminance is 0.3347 and perceived brightness is 60%, so black text on it reaches 7.69:1.

Should I use black or white text on #84a39b?

Black. It scores 7.69:1 against #84a39b, versus 2.73:1 for white — AAA at any size.

Is #84a39b accessible on a white background?

#84a39b on white scores 2.73:1, which fails WCAG AA at every size. Darken it to #5D7D75 to reach 4.5:1, or #455D57 for 7:1.

What is the complementary color of #84a39b?

#A3848C sits directly opposite on the wheel. Softer options are the split-complements #A3849B and #A38B84, which give the same contrast with far less vibration.

What colors go well with #84a39b?

For interface work: #F6F8F8 as the surface, #D0DCD9 for borders, #62837B for secondary text, #A78094 as an accent and #374944 for hover and pressed states. For a palette, the analogous pair #84A38B and #849BA3 stays calm, while #A3848C is the loudest partner.

What is #84a39b in CMYK for printing?

cmyk(19%, 0%, 5%, 36%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #84a39b warm or cool?

Cool — it scores 63 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #84A390; nudged cooler, #82A1A5.

Which Tailwind color is closest to #84a39b?

The teal family — its 500 step is #14b8a6, ΔE2000 14.2 away. That is a visible difference, so define #84a39b as a custom token rather than reaching for the built-in.

How do I use #84a39b in Tailwind CSS?

Inline it as an arbitrary value with bg-[#84a39b] or text-[#84a39b], 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 #84a39b with 50% opacity?
