How to use #a3b2ac

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

Works well for
  • Text and icons on dark surfaces
  • Borders, dividers and quiet backgrounds
  • Long-form reading 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 #3A4541
Safe as a 1px border on white
No — use #859991

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.

With almost no chroma left, the family association is barely present; treat it as a neutral that happens to lean this way. 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.

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.

#a3b2ac, answered

What color is #a3b2ac?

#a3b2ac is a light muted green, closest to Dark Gray (ΔE2000 8.1). It sits at 156° on the hue wheel with 9% saturation and 67% lightness, which reads as neutral.

What is the RGB value of #a3b2ac?

rgb(163, 178, 172) — 163 red, 178 green and 172 blue out of 255, or 63.9% / 69.8% / 67.5% by channel.

What is #a3b2ac in HSL and HSV?

hsl(156, 9%, 67%) and hsv(156, 8%, 70%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a3b2ac a light or a dark color?

It is a mid-tone. Relative luminance is 0.4261 and perceived brightness is 68%, so black text on it reaches 9.52:1.

Should I use black or white text on #a3b2ac?

Black. It scores 9.52:1 against #a3b2ac, versus 2.21:1 for white — AAA at any size.

Is #a3b2ac accessible on a white background?

#a3b2ac on white scores 2.21:1, which fails WCAG AA at every size. Darken it to #667A72 to reach 4.5:1, or #4C5B55 for 7:1.

What is the complementary color of #a3b2ac?

#B2A3A9 sits directly opposite on the wheel. Softer options are the split-complements #B2A3B1 and #B2A5A3, which give the same contrast with far less vibration.

What colors go well with #a3b2ac?

For interface work: #F7F8F7 as the surface, #D3DAD7 for borders, #697D75 for secondary text, #73596A as an accent and #3A4541 for hover and pressed states. For a palette, the analogous pair #A3B2A5 and #A3B1B2 stays calm, while #B2A3A9 is the loudest partner.

What is #a3b2ac in CMYK for printing?

cmyk(8%, 0%, 3%, 30%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a3b2ac warm or cool?

Neutral — it scores 57 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #BBAEA5; nudged cooler, #99A5B2.

Which Tailwind color is closest to #a3b2ac?

The teal family — its 500 step is #14b8a6, ΔE2000 18.7 away. That is a visible difference, so define #a3b2ac as a custom token rather than reaching for the built-in.

How do I use #a3b2ac in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a3b2ac] or text-[#a3b2ac], 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 #a3b2ac with 50% opacity?

rgba(163, 178, 172, 0.5), or #a3b2ac80 in eight-digit hex. Over white that composites to #D1D9D6; over black, #525956.

Is #a3b2ac a web-safe color?

No. The nearest web-safe colour is #999999, ΔE2000 10.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #a3b2ac mean?
