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 #afd55e

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #4D651A
Safe as a 1px border on white
No — use #799F29

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 mid lightness keeps it versatile in both themes.

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 #afd55e 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.

#afd55e, answered

What color is #afd55e?

#afd55e is a balanced vivid green, closest to Yellow Green (ΔE2000 4.5). It sits at 79° on the hue wheel with 59% saturation and 60% lightness, which reads as warm.

What is the RGB value of #afd55e?

rgb(175, 213, 94) — 175 red, 213 green and 94 blue out of 255, or 68.6% / 83.5% / 36.9% by channel.

What is #afd55e in HSL and HSV?

hsl(79, 59%, 60%) and hsv(79, 56%, 84%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #afd55e a light or a dark color?

It is a light color. Relative luminance is 0.5751 and perceived brightness is 75%, so black text on it reaches 12.50:1.

Should I use black or white text on #afd55e?

Black. It scores 12.50:1 against #afd55e, versus 1.68:1 for white — AAA at any size.

Is #afd55e accessible on a white background?

#afd55e on white scores 1.68:1, which fails WCAG AA at every size. Darken it to #607E21 to reach 4.5:1, or #485E18 for 7:1.

What is the complementary color of #afd55e?

#845ED5 sits directly opposite on the wheel. Softer options are the split-complements #5E73D5 and #C05ED5, which give the same contrast with far less vibration.

What colors go well with #afd55e?

For interface work: #F8FAF4 as the surface, #DEEDC0 for borders, #819B4B for secondary text, #635AD9 as an accent and #4D651A for hover and pressed states. For a palette, the analogous pair #D5C05E and #73D55E stays calm, while #845ED5 is the loudest partner.

What is #afd55e in CMYK for printing?

cmyk(18%, 0%, 56%, 17%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #afd55e warm or cool?

Warm — it scores 41 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #D5CF5E; nudged cooler, #83D75C.

Which Tailwind color is closest to #afd55e?

The lime family — its 500 step is #84cc16, ΔE2000 7.1 away. That is a visible difference, so define #afd55e as a custom token rather than reaching for the built-in.

How do I use #afd55e in Tailwind CSS?

Inline it as an arbitrary value with bg-[#afd55e] or text-[#afd55e], 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 #afd55e with 50% opacity?

rgba(175, 213, 94, 0.5), or #afd55e80 in eight-digit hex. Over white that composites to #D7EAAF; over black, #586B2F.

Is #afd55e a web-safe color?

No. The nearest web-safe colour is #99CC66, ΔE2000 4.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #afd55e 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 #afd55e?
