How to use #8ea59f

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 #394743
Safe as a 1px border on white
No — use #809A93

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.

Transparency

What each alpha value actually composites to. The top row is #8ea59f 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.

#8ea59f, answered

What color is #8ea59f?

#8ea59f is a balanced muted cyan, closest to Cadet Blue (ΔE2000 10). It sits at 164° on the hue wheel with 11% saturation and 60% lightness, which reads as cool.

What is the RGB value of #8ea59f?

rgb(142, 165, 159) — 142 red, 165 green and 159 blue out of 255, or 55.7% / 64.7% / 62.4% by channel.

What is #8ea59f in HSL and HSV?

hsl(164, 11%, 60%) and hsv(164, 14%, 65%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8ea59f a light or a dark color?

It is a mid-tone. Relative luminance is 0.3516 and perceived brightness is 62%, so black text on it reaches 8.03:1.

Should I use black or white text on #8ea59f?

Black. It scores 8.03:1 against #8ea59f, versus 2.61:1 for white — AAA at any size.

Is #8ea59f accessible on a white background?

#8ea59f on white scores 2.61:1, which fails WCAG AA at every size. Darken it to #627B74 to reach 4.5:1, or #495B57 for 7:1.

What is the complementary color of #8ea59f?

#A58E94 sits directly opposite on the wheel. Softer options are the split-complements #A58EA0 and #A5948E, which give the same contrast with far less vibration.

What colors go well with #8ea59f?

For interface work: #F6F8F8 as the surface, #D2DBD8 for borders, #668079 for secondary text, #765667 as an accent and #394743 for hover and pressed states. For a palette, the analogous pair #8EA594 and #8EA0A5 stays calm, while #A58E94 is the loudest partner.

What is #8ea59f in CMYK for printing?

cmyk(14%, 0%, 4%, 35%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #8ea59f warm or cool?

Cool — it scores 60 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8EA597; nudged cooler, #8CA4A7.

Which Tailwind color is closest to #8ea59f?

The teal family — its 500 step is #14b8a6, ΔE2000 16.2 away. That is a visible difference, so define #8ea59f as a custom token rather than reaching for the built-in.

How do I use #8ea59f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8ea59f] or text-[#8ea59f], 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 #8ea59f with 50% opacity?

rgba(142, 165, 159, 0.5), or #8ea59f80 in eight-digit hex. Over white that composites to #C7D2CF; over black, #475350.

Is #8ea59f 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.
