How to use #8da8af

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 #35464B
Safe as a 1px border on white
No — use #7B9AA2

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.

What each alpha value actually composites to. The top row is #8da8af 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.

#8da8af, answered

What color is #8da8af?

#8da8af is a balanced soft cyan, closest to Cadet Blue (ΔE2000 10.4). It sits at 192° on the hue wheel with 18% saturation and 62% lightness, which reads as cool.

What is the RGB value of #8da8af?

rgb(141, 168, 175) — 141 red, 168 green and 175 blue out of 255, or 55.3% / 65.9% / 68.6% by channel.

What is #8da8af in HSL and HSV?

hsl(192, 18%, 62%) and hsv(192, 19%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8da8af a light or a dark color?

It is a mid-tone. Relative luminance is 0.3676 and perceived brightness is 63%, so black text on it reaches 8.35:1.

Should I use black or white text on #8da8af?

Black. It scores 8.35:1 against #8da8af, versus 2.51:1 for white — AAA at any size.

Is #8da8af accessible on a white background?

#8da8af on white scores 2.51:1, which fails WCAG AA at every size. Darken it to #5A7981 to reach 4.5:1, or #455D63 for 7:1.

What is the complementary color of #8da8af?

#AF948D sits directly opposite on the wheel. Softer options are the split-complements #AF8D97 and #AFA58D, which give the same contrast with far less vibration.

What colors go well with #8da8af?

For interface work: #F6F8F9 as the surface, #CFDADD for borders, #5F7F87 for secondary text, #7C5052 as an accent and #35464B for hover and pressed states. For a palette, the analogous pair #8DAFA5 and #8D97AF stays calm, while #AF948D is the loudest partner.

What is #8da8af in CMYK for printing?

cmyk(19%, 4%, 0%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #8da8af 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 #8DAFAA; nudged cooler, #8B9FB1.

Which Tailwind color is closest to #8da8af?

The cyan family — its 500 step is #06b6d4, ΔE2000 13.8 away. That is a visible difference, so define #8da8af as a custom token rather than reaching for the built-in.

How do I use #8da8af in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8da8af] or text-[#8da8af], 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 #8da8af with 50% opacity?

rgba(141, 168, 175, 0.5), or #8da8af80 in eight-digit hex. Over white that composites to #C6D4D7; over black, #475458.

Is #8da8af a web-safe color?

No. The nearest web-safe colour is #999999, ΔE2000 10.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #8da8af 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 #8da8af?

The safest is same-hue elevation: linear-gradient(135deg, #B1C4C8, #8da8af 45%, #35464B). For more colour, a short hue run to #7B7DA2 keeps it rich without turning muddy.
