How to use #809c97

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 #384845
Safe as a 1px border on white
No — use #7D9A95

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.

  • EnergyLow
  • Weight44/100

#809c97, answered

What color is #809c97?

#809c97 is a balanced muted cyan, closest to Cadet Blue (ΔE2000 7.7). It sits at 169° on the hue wheel with 12% saturation and 56% lightness, which reads as cool.

What is the RGB value of #809c97?

rgb(128, 156, 151) — 128 red, 156 green and 151 blue out of 255, or 50.2% / 61.2% / 59.2% by channel.

What is #809c97 in HSL and HSV?

hsl(169, 12%, 56%) and hsv(169, 18%, 61%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #809c97 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3060 and perceived brightness is 58%, so black text on it reaches 7.12:1.

Should I use black or white text on #809c97?

Black. It scores 7.12:1 against #809c97, versus 2.95:1 for white — AAA at any size.

Is #809c97 accessible on a white background?

#809c97 on white scores 2.95:1, which fails WCAG AA at every size. Darken it to #5F7A76 to reach 4.5:1, or #475B57 for 7:1.

What is the complementary color of #809c97?

#9C8085 sits directly opposite on the wheel. Softer options are the split-complements #9C8093 and #9C8980, which give the same contrast with far less vibration.

What colors go well with #809c97?

For interface work: #F6F8F8 as the surface, #D1DBD9 for borders, #65817C for secondary text, #A17C8B as an accent and #384845 for hover and pressed states. For a palette, the analogous pair #809C89 and #80939C stays calm, while #9C8085 is the loudest partner.

What is #809c97 in CMYK for printing?

cmyk(18%, 0%, 3%, 39%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #809c97 warm or cool?

Cool — it scores 62 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #809C8D; nudged cooler, #7E989E.

Which Tailwind color is closest to #809c97?

The teal family — its 500 step is #14b8a6, ΔE2000 15.6 away. That is a visible difference, so define #809c97 as a custom token rather than reaching for the built-in.

How do I use #809c97 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#809c97] or text-[#809c97], 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 #809c97 with 50% opacity?
