How to use #8eb78f

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
  • Status meaning — pair it with an icon or label, never colour alone
  • 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 #324E32
Safe as a 1px border on white
No — use #6CA16D

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

safegrowingnaturalpermissive

Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.

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

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

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.

#8eb78f, answered

What color is #8eb78f?

#8eb78f is a balanced soft green, closest to Dark Sea Green (ΔE2000 1.8). It sits at 122° on the hue wheel with 22% saturation and 64% lightness, which reads as cool.

What is the RGB value of #8eb78f?

rgb(142, 183, 143) — 142 red, 183 green and 143 blue out of 255, or 55.7% / 71.8% / 56.1% by channel.

What is #8eb78f in HSL and HSV?

hsl(122, 22%, 64%) and hsv(121, 22%, 72%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8eb78f a light or a dark color?

It is a mid-tone. Relative luminance is 0.4160 and perceived brightness is 66%, so black text on it reaches 9.32:1.

Should I use black or white text on #8eb78f?

Black. It scores 9.32:1 against #8eb78f, versus 2.25:1 for white — AAA at any size.

Is #8eb78f accessible on a white background?

#8eb78f on white scores 2.25:1, which fails WCAG AA at every size. Darken it to #517F52 to reach 4.5:1, or #3D603E for 7:1.

What is the complementary color of #8eb78f?

#B78EB6 sits directly opposite on the wheel. Softer options are the split-complements #A38EB7 and #B78EA1, which give the same contrast with far less vibration.

What colors go well with #8eb78f?

For interface work: #F6F9F6 as the surface, #CDDFCE for borders, #598C5B for secondary text, #754B81 as an accent and #324E32 for hover and pressed states. For a palette, the analogous pair #A1B78E and #8EB7A3 stays calm, while #B78EB6 is the loudest partner.

What is #8eb78f in CMYK for printing?

cmyk(22%, 0%, 22%, 28%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #8eb78f warm or cool?

Cool — it scores 58 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #9CB78E; nudged cooler, #8CB99E.

Which Tailwind color is closest to #8eb78f?

The emerald family — its 500 step is #10b981, ΔE2000 12.2 away. That is a visible difference, so define #8eb78f as a custom token rather than reaching for the built-in.

How do I use #8eb78f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8eb78f] or text-[#8eb78f], 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 #8eb78f with 50% opacity?

rgba(142, 183, 143, 0.5), or #8eb78f80 in eight-digit hex. Over white that composites to #C7DBC7; over black, #475C48.

Is #8eb78f a web-safe color?

No. The nearest web-safe colour is #99CC99, ΔE2000 5.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #8eb78f mean?
