Colour vision deficiency

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 #acebc4

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 #196737
Safe as a 1px border on white
No — use #28A859

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 #acebc4 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.

#acebc4, answered

What color is #acebc4?

#acebc4 is a light vivid green, closest to Aqua Marine (ΔE2000 8). It sits at 143° on the hue wheel with 61% saturation and 80% lightness, which reads as cool.

What is the RGB value of #acebc4?

rgb(172, 235, 196) — 172 red, 235 green and 196 blue out of 255, or 67.5% / 92.2% / 76.9% by channel.

What is #acebc4 in HSL and HSV?

hsl(143, 61%, 80%) and hsv(143, 27%, 92%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #acebc4 a light or a dark color?

It is a light color. Relative luminance is 0.7217 and perceived brightness is 84%, so black text on it reaches 15.43:1.

Should I use black or white text on #acebc4?

Black. It scores 15.43:1 against #acebc4, versus 1.36:1 for white — AAA at any size.

Is #acebc4 accessible on a white background?

#acebc4 on white scores 1.36:1, which fails WCAG AA at every size. Darken it to #208748 to reach 4.5:1, or #196636 for 7:1.

What is the complementary color of #acebc4?

#EBACD3 sits directly opposite on the wheel. Softer options are the split-complements #E4ACEB and #EBACB3, which give the same contrast with far less vibration.

What colors go well with #acebc4?

For interface work: #F4FAF7 as the surface, #C0EDD1 for borders, #4B9B69 for secondary text, #A82496 as an accent and #196737 for hover and pressed states. For a palette, the analogous pair #B3EBAC and #ACEBE4 stays calm, while #EBACD3 is the loudest partner.

What is #acebc4 in CMYK for printing?

cmyk(27%, 0%, 17%, 8%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #acebc4 warm or cool?

Cool — it scores 72 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #ACEBAD; nudged cooler, #ABECDC.

Which Tailwind color is closest to #acebc4?

The emerald family — its 500 step is #10b981, ΔE2000 17.5 away. That is a visible difference, so define #acebc4 as a custom token rather than reaching for the built-in.

How do I use #acebc4 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#acebc4] or text-[#acebc4], 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 #acebc4 with 50% opacity?

rgba(172, 235, 196, 0.5), or #acebc480 in eight-digit hex. Over white that composites to #D6F5E2; over black, #567662.

Is #acebc4 a web-safe color?

No. The nearest web-safe colour is #99FFCC, ΔE2000 6 away. The palette only matters for legacy displays and some email clients now.

What does the color #acebc4 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 #acebc4?

The safest is same-hue elevation: linear-gradient(135deg, #DDF7E7, #acebc4 45%, #196737). For more colour, a short hue run to #93DAE5 keeps it rich without turning muddy.
