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 #adefa1

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 #206D13
Safe as a 1px border on white
No — use #32A71C

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

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.

#adefa1, answered

What color is #adefa1?

#adefa1 is a light vivid green, closest to Light Green (ΔE2000 4.1). It sits at 111° on the hue wheel with 71% saturation and 78% lightness, which reads as cool.

What is the RGB value of #adefa1?

rgb(173, 239, 161) — 173 red, 239 green and 161 blue out of 255, or 67.8% / 93.7% / 63.1% by channel.

What is #adefa1 in HSL and HSV?

hsl(111, 71%, 78%) and hsv(111, 33%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #adefa1 a light or a dark color?

It is a light color. Relative luminance is 0.7319 and perceived brightness is 84%, so black text on it reaches 15.64:1.

Should I use black or white text on #adefa1?

Black. It scores 15.64:1 against #adefa1, versus 1.34:1 for white — AAA at any size.

Is #adefa1 accessible on a white background?

#adefa1 on white scores 1.34:1, which fails WCAG AA at every size. Darken it to #278417 to reach 4.5:1, or #1E6611 for 7:1.

What is the complementary color of #adefa1?

#E3A1EF sits directly opposite on the wheel. Softer options are the split-complements #BCA1EF and #EFA1D4, which give the same contrast with far less vibration.

What colors go well with #adefa1?

For interface work: #F5FAF4 as the surface, #C7EDC0 for borders, #579B4B for secondary text, #751AB2 as an accent and #206D13 for hover and pressed states. For a palette, the analogous pair #D4EFA1 and #A1EFBC stays calm, while #E3A1EF is the loudest partner.

What is #adefa1 in CMYK for printing?

cmyk(28%, 0%, 33%, 6%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #adefa1 warm or cool?

Cool — it scores 59 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #C9EFA1; nudged cooler, #A0F0B1.

Which Tailwind color is closest to #adefa1?

The green family — its 500 step is #22c55e, ΔE2000 15.1 away. That is a visible difference, so define #adefa1 as a custom token rather than reaching for the built-in.

How do I use #adefa1 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#adefa1] or text-[#adefa1], 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 #adefa1 with 50% opacity?

rgba(173, 239, 161, 0.5), or #adefa180 in eight-digit hex. Over white that composites to #D6F7D0; over black, #577851.

Is #adefa1 a web-safe color?

No. The nearest web-safe colour is #99FF99, ΔE2000 5.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #adefa1 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 #adefa1?

The safest is same-hue elevation: linear-gradient(135deg, #DAF8D5, #adefa1 45%, #206D13). For more colour, a short hue run to #87EBC2 keeps it rich without turning muddy.
