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 #a3cdac

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 #2D5335
Safe as a 1px border on white
No — use #58A368

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 #a3cdac 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.

#a3cdac, answered

What color is #a3cdac?

#a3cdac is a light soft green, closest to Dark Sea Green (ΔE2000 5.9). It sits at 133° on the hue wheel with 30% saturation and 72% lightness, which reads as cool.

What is the RGB value of #a3cdac?

rgb(163, 205, 172) — 163 red, 205 green and 172 blue out of 255, or 63.9% / 80.4% / 67.5% by channel.

What is #a3cdac in HSL and HSV?

hsl(133, 30%, 72%) and hsv(133, 20%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a3cdac a light or a dark color?

It is a light color. Relative luminance is 0.5443 and perceived brightness is 74%, so black text on it reaches 11.89:1.

Should I use black or white text on #a3cdac?

Black. It scores 11.89:1 against #a3cdac, versus 1.77:1 for white — AAA at any size.

Is #a3cdac accessible on a white background?

#a3cdac on white scores 1.77:1, which fails WCAG AA at every size. Darken it to #468253 to reach 4.5:1, or #34613E for 7:1.

What is the complementary color of #a3cdac?

#CDA3C4 sits directly opposite on the wheel. Softer options are the split-complements #C1A3CD and #CDA3AF, which give the same contrast with far less vibration.

What colors go well with #a3cdac?

For interface work: #F5FAF6 as the surface, #CAE2CF for borders, #51955F for secondary text, #864488 as an accent and #2D5335 for hover and pressed states. For a palette, the analogous pair #AFCDA3 and #A3CDC1 stays calm, while #CDA3C4 is the loudest partner.

What is #a3cdac in CMYK for printing?

cmyk(21%, 0%, 16%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a3cdac warm or cool?

Cool — it scores 65 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A9CDA3; nudged cooler, #A2CFBC.

Which Tailwind color is closest to #a3cdac?

The emerald family — its 500 step is #10b981, ΔE2000 15.1 away. That is a visible difference, so define #a3cdac as a custom token rather than reaching for the built-in.

How do I use #a3cdac in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a3cdac] or text-[#a3cdac], 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 #a3cdac with 50% opacity?

rgba(163, 205, 172, 0.5), or #a3cdac80 in eight-digit hex. Over white that composites to #D1E6D6; over black, #526756.

Is #a3cdac a web-safe color?

No. The nearest web-safe colour is #99CC99, ΔE2000 4.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #a3cdac 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 #a3cdac?
