Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

Color scale — 50 to 950

How to use #8adeb5

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • White text placed on it
  • 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 #1C6341
Safe as a 1px border on white
No — use #2FA56B

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The lightness keeps it airy and approachable.

Worth knowing

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

Transparency

What each alpha value actually composites to. The top row is #8adeb5 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.

#8adeb5, answered

What color is #8adeb5?

#8adeb5 is a light vivid green, closest to Medium Aqua Marine (ΔE2000 5.5). It sits at 151° on the hue wheel with 56% saturation and 71% lightness, which reads as cool.

What is the RGB value of #8adeb5?

rgb(138, 222, 181) — 138 red, 222 green and 181 blue out of 255, or 54.1% / 87.1% / 71% by channel.

What is #8adeb5 in HSL and HSV?

hsl(151, 56%, 71%) and hsv(151, 38%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8adeb5 a light or a dark color?

It is a light color. Relative luminance is 0.6098 and perceived brightness is 77%, so black text on it reaches 13.20:1.

Should I use black or white text on #8adeb5?

Black. It scores 13.20:1 against #8adeb5, versus 1.59:1 for white — AAA at any size.

Is #8adeb5 accessible on a white background?

#8adeb5 on white scores 1.59:1, which fails WCAG AA at every size. Darken it to #268657 to reach 4.5:1, or #1C6240 for 7:1.

What is the complementary color of #8adeb5?

#DE8AB3 sits directly opposite on the wheel. Softer options are the split-complements #DE8ADD and #DE8B8A, which give the same contrast with far less vibration.

What colors go well with #8adeb5?

For interface work: #F4FAF7 as the surface, #C0EDD7 for borders, #4B9B74 for secondary text, #A32983 as an accent and #1C6341 for hover and pressed states. For a palette, the analogous pair #8ADE8B and #8ADDDE stays calm, while #DE8AB3 is the loudest partner.

What is #8adeb5 in CMYK for printing?

cmyk(38%, 0%, 19%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #8adeb5 warm or cool?

Cool — it scores 75 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8ADE96; nudged cooler, #89E0D5.

Which Tailwind color is closest to #8adeb5?

The emerald family — its 500 step is #10b981, ΔE2000 12.9 away. That is a visible difference, so define #8adeb5 as a custom token rather than reaching for the built-in.

How do I use #8adeb5 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8adeb5] or text-[#8adeb5], 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 #8adeb5 with 50% opacity?

rgba(138, 222, 181, 0.5), or #8adeb580 in eight-digit hex. Over white that composites to #C5EFDA; over black, #456F5B.

Is #8adeb5 a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 14.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #8adeb5 mean?

As a green, it reads safe, growing, natural. Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #8adeb5?
