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 #a1cfba

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 #2B5442
Safe as a 1px border on white
No — use #53A37E

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 #a1cfba 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.

#a1cfba, answered

What color is #a1cfba?

#a1cfba is a light soft green, closest to Medium Aqua Marine (ΔE2000 8.9). It sits at 153° on the hue wheel with 32% saturation and 72% lightness, which reads as cool.

What is the RGB value of #a1cfba?

rgb(161, 207, 186) — 161 red, 207 green and 186 blue out of 255, or 63.1% / 81.2% / 72.9% by channel.

What is #a1cfba in HSL and HSV?

hsl(153, 32%, 72%) and hsv(153, 22%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a1cfba a light or a dark color?

It is a light color. Relative luminance is 0.5575 and perceived brightness is 75%, so black text on it reaches 12.15:1.

Should I use black or white text on #a1cfba?

Black. It scores 12.15:1 against #a1cfba, versus 1.73:1 for white — AAA at any size.

Is #a1cfba accessible on a white background?

#a1cfba on white scores 1.73:1, which fails WCAG AA at every size. Darken it to #428164 to reach 4.5:1, or #315F4A for 7:1.

What is the complementary color of #a1cfba?

#CFA1B6 sits directly opposite on the wheel. Softer options are the split-complements #CFA1CD and #CFA3A1, which give the same contrast with far less vibration.

What colors go well with #a1cfba?

For interface work: #F5FAF8 as the surface, #C9E3D7 for borders, #4E9876 for secondary text, #8B4176 as an accent and #2B5442 for hover and pressed states. For a palette, the analogous pair #A1CFA3 and #A1CDCF stays calm, while #CFA1B6 is the loudest partner.

What is #a1cfba in CMYK for printing?

cmyk(22%, 0%, 10%, 19%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a1cfba warm or cool?

Cool — it scores 74 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A1CFA9; nudged cooler, #A0D0CC.

Which Tailwind color is closest to #a1cfba?

The teal family — its 500 step is #14b8a6, ΔE2000 14.4 away. That is a visible difference, so define #a1cfba as a custom token rather than reaching for the built-in.

How do I use #a1cfba in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a1cfba] or text-[#a1cfba], 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 #a1cfba with 50% opacity?

rgba(161, 207, 186, 0.5), or #a1cfba80 in eight-digit hex. Over white that composites to #D0E7DD; over black, #51685D.

Is #a1cfba a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 8.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #a1cfba 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 #a1cfba?
