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 #acffd6

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 #008041
Safe as a 1px border on white
No — use #00A754

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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.

#acffd6, answered

What color is #acffd6?

#acffd6 is a light electric green, closest to Aqua Marine (ΔE2000 5). It sits at 150° on the hue wheel with 100% saturation and 84% lightness, which reads as cool.

What is the RGB value of #acffd6?

rgb(172, 255, 214) — 172 red, 255 green and 214 blue out of 255, or 67.5% / 100% / 83.9% by channel.

What is #acffd6 in HSL and HSV?

hsl(150, 100%, 84%) and hsv(150, 33%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #acffd6 a light or a dark color?

It is a light color. Relative luminance is 0.8515 and perceived brightness is 90%, so black text on it reaches 18.03:1.

Should I use black or white text on #acffd6?

Black. It scores 18.03:1 against #acffd6, versus 1.16:1 for white — AAA at any size.

Is #acffd6 accessible on a white background?

#acffd6 on white scores 1.16:1, which fails WCAG AA at every size. Darken it to #008845 to reach 4.5:1, or #006433 for 7:1.

What is the complementary color of #acffd6?

#FFACD5 sits directly opposite on the wheel. Softer options are the split-complements #FFACFE and #FFACAC, which give the same contrast with far less vibration.

What colors go well with #acffd6?

For interface work: #F4FAF7 as the surface, #C0EDD6 for borders, #4B9B73 for secondary text, #CC0098 as an accent and #008041 for hover and pressed states. For a palette, the analogous pair #ACFFAC and #ACFEFF stays calm, while #FFACD5 is the loudest partner.

What is #acffd6 in CMYK for printing?

cmyk(33%, 0%, 16%, 0%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #acffd6 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 #ACFFB8; nudged cooler, #ACFFF4.

Which Tailwind color is closest to #acffd6?

The emerald family — its 500 step is #10b981, ΔE2000 19.8 away. That is a visible difference, so define #acffd6 as a custom token rather than reaching for the built-in.

How do I use #acffd6 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#acffd6] or text-[#acffd6], 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 #acffd6 with 50% opacity?

rgba(172, 255, 214, 0.5), or #acffd680 in eight-digit hex. Over white that composites to #D6FFEB; over black, #56806B.

Is #acffd6 a web-safe color?

No. The nearest web-safe colour is #99FFCC, ΔE2000 3 away. The palette only matters for legacy displays and some email clients now.

What does the color #acffd6 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 #acffd6?

The safest is same-hue elevation: linear-gradient(135deg, #E9FFF4, #acffd6 45%, #008041). For more colour, a short hue run to #8DE2FF keeps it rich without turning muddy.
