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.

How to use #acd466

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #4A641C
Safe as a 1px border on white
No — use #77A22D

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 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.

Transparency

What each alpha value actually composites to. The top row is #acd466 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.

#acd466, answered

What color is #acd466?

#acd466 is a balanced vivid green, closest to Yellow Green (ΔE2000 5.3). It sits at 82° on the hue wheel with 56% saturation and 62% lightness, which reads as neutral.

What is the RGB value of #acd466?

rgb(172, 212, 102) — 172 red, 212 green and 102 blue out of 255, or 67.5% / 83.1% / 40% by channel.

What is #acd466 in HSL and HSV?

hsl(82, 56%, 62%) and hsv(82, 52%, 83%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #acd466 a light or a dark color?

It is a light color. Relative luminance is 0.5682 and perceived brightness is 75%, so black text on it reaches 12.36:1.

Should I use black or white text on #acd466?

Black. It scores 12.36:1 against #acd466, versus 1.70:1 for white — AAA at any size.

Is #acd466 accessible on a white background?

#acd466 on white scores 1.70:1, which fails WCAG AA at every size. Darken it to #5D7E23 to reach 4.5:1, or #455E1A for 7:1.

What is the complementary color of #acd466?

#8E66D4 sits directly opposite on the wheel. Softer options are the split-complements #6675D4 and #C566D4, which give the same contrast with far less vibration.

What colors go well with #acd466?

For interface work: #F8FAF4 as the surface, #DCEDC0 for borders, #7E9B4B for secondary text, #7062D8 as an accent and #4A641C for hover and pressed states. For a palette, the analogous pair #D4C566 and #75D466 stays calm, while #8E66D4 is the loudest partner.

What is #acd466 in CMYK for printing?

cmyk(19%, 0%, 52%, 17%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #acd466 warm or cool?

Neutral — it scores 43 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D4D466; nudged cooler, #83D664.

Which Tailwind color is closest to #acd466?

The lime family — its 500 step is #84cc16, ΔE2000 7.5 away. That is a visible difference, so define #acd466 as a custom token rather than reaching for the built-in.

How do I use #acd466 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#acd466] or text-[#acd466], 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 #acd466 with 50% opacity?

rgba(172, 212, 102, 0.5), or #acd46680 in eight-digit hex. Over white that composites to #D6EAB3; over black, #566A33.

Is #acd466 a web-safe color?

No. The nearest web-safe colour is #99CC66, ΔE2000 3.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #acd466 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 #acd466?
