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 #afe9bc

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 #1B642C
Safe as a 1px border on white
No — use #2EA849

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.

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.

#afe9bc, answered

What color is #afe9bc?

#afe9bc is a light vivid green, closest to Aqua Marine (ΔE2000 9.3). It sits at 133° on the hue wheel with 57% saturation and 80% lightness, which reads as cool.

What is the RGB value of #afe9bc?

rgb(175, 233, 188) — 175 red, 233 green and 188 blue out of 255, or 68.6% / 91.4% / 73.7% by channel.

What is #afe9bc in HSL and HSV?

hsl(133, 57%, 80%) and hsv(133, 25%, 91%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #afe9bc a light or a dark color?

It is a light color. Relative luminance is 0.7102 and perceived brightness is 83%, so black text on it reaches 15.20:1.

Should I use black or white text on #afe9bc?

Black. It scores 15.20:1 against #afe9bc, versus 1.38:1 for white — AAA at any size.

Is #afe9bc accessible on a white background?

#afe9bc on white scores 1.38:1, which fails WCAG AA at every size. Darken it to #25883B to reach 4.5:1, or #1B642C for 7:1.

What is the complementary color of #afe9bc?

#E9AFDC sits directly opposite on the wheel. Softer options are the split-complements #D9AFE9 and #E9AFBF, which give the same contrast with far less vibration.

What colors go well with #afe9bc?

For interface work: #F4FAF6 as the surface, #C0EDCA for borders, #4B9B5D for secondary text, #A028A4 as an accent and #1B642C for hover and pressed states. For a palette, the analogous pair #BFE9AF and #AFE9D9 stays calm, while #E9AFDC is the loudest partner.

What is #afe9bc in CMYK for printing?

cmyk(25%, 0%, 19%, 9%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #afe9bc warm or cool?

Cool — it scores 68 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B7E9AF; nudged cooler, #AEEAD1.

Which Tailwind color is closest to #afe9bc?

The emerald family — its 500 step is #10b981, ΔE2000 17.4 away. That is a visible difference, so define #afe9bc as a custom token rather than reaching for the built-in.

How do I use #afe9bc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#afe9bc] or text-[#afe9bc], 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 #afe9bc with 50% opacity?

rgba(175, 233, 188, 0.5), or #afe9bc80 in eight-digit hex. Over white that composites to #D7F4DE; over black, #58755E.

Is #afe9bc a web-safe color?

No. The nearest web-safe colour is #99FFCC, ΔE2000 6.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #afe9bc 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 #afe9bc?

The safest is same-hue elevation: linear-gradient(135deg, #DFF6E4, #afe9bc 45%, #1B642C). For more colour, a short hue run to #97E2E0 keeps it rich without turning muddy.
