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 #acd9ba

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #285737
Safe as a 1px border on white
No — use #4CA568

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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 #acd9ba 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.

#acd9ba, answered

What color is #acd9ba?

#acd9ba is a light soft green, closest to Dark Sea Green (ΔE2000 8.8). It sits at 139° on the hue wheel with 37% saturation and 76% lightness, which reads as cool.

What is the RGB value of #acd9ba?

rgb(172, 217, 186) — 172 red, 217 green and 186 blue out of 255, or 67.5% / 85.1% / 72.9% by channel.

What is #acd9ba in HSL and HSV?

hsl(139, 37%, 76%) and hsv(139, 21%, 85%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #acd9ba a light or a dark color?

It is a light color. Relative luminance is 0.6194 and perceived brightness is 79%, so black text on it reaches 13.39:1.

Should I use black or white text on #acd9ba?

Black. It scores 13.39:1 against #acd9ba, versus 1.57:1 for white — AAA at any size.

Is #acd9ba accessible on a white background?

#acd9ba on white scores 1.57:1, which fails WCAG AA at every size. Darken it to #3C8252 to reach 4.5:1, or #2D633E for 7:1.

What is the complementary color of #acd9ba?

#D9ACCB sits directly opposite on the wheel. Softer options are the split-complements #D1ACD9 and #D9ACB5, which give the same contrast with far less vibration.

What colors go well with #acd9ba?

For interface work: #F5FAF6 as the surface, #C7E5D0 for borders, #4B9B64 for secondary text, #8F3D8A as an accent and #285737 for hover and pressed states. For a palette, the analogous pair #B5D9AC and #ACD9D1 stays calm, while #D9ACCB is the loudest partner.

What is #acd9ba in CMYK for printing?

cmyk(21%, 0%, 14%, 15%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #acd9ba warm or cool?

Cool — it scores 70 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AFD9AC; nudged cooler, #ABDACB.

Which Tailwind color is closest to #acd9ba?

The emerald family — its 500 step is #10b981, ΔE2000 16.7 away. That is a visible difference, so define #acd9ba as a custom token rather than reaching for the built-in.

How do I use #acd9ba in Tailwind CSS?

Inline it as an arbitrary value with bg-[#acd9ba] or text-[#acd9ba], 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 #acd9ba with 50% opacity?

rgba(172, 217, 186, 0.5), or #acd9ba80 in eight-digit hex. Over white that composites to #D6ECDD; over black, #566D5D.

Is #acd9ba a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 11.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #acd9ba 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 moderate chroma the association is present but not shouted.

What gradient works with #acd9ba?

The safest is same-hue elevation: linear-gradient(135deg, #D6ECDD, #acd9ba 45%, #285737). For more colour, a short hue run to #97CCCF keeps it rich without turning muddy.
