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.

Color scale — 50 to 950

How to use #aef32f

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 #517907
Safe as a 1px border on white
No — use #6DA309

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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.

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.

#aef32f, answered

What color is #aef32f?

#aef32f is a balanced electric green, closest to Green Yellow (ΔE2000 2.6). It sits at 81° on the hue wheel with 89% saturation and 57% lightness, which reads as neutral.

What is the RGB value of #aef32f?

rgb(174, 243, 47) — 174 red, 243 green and 47 blue out of 255, or 68.2% / 95.3% / 18.4% by channel.

What is #aef32f in HSL and HSV?

hsl(81, 89%, 57%) and hsv(81, 81%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aef32f a light or a dark color?

It is a light color. Relative luminance is 0.7331 and perceived brightness is 82%, so black text on it reaches 15.66:1.

Should I use black or white text on #aef32f?

Black. It scores 15.66:1 against #aef32f, versus 1.34:1 for white — AAA at any size.

Is #aef32f accessible on a white background?

#aef32f on white scores 1.34:1, which fails WCAG AA at every size. Darken it to #578207 to reach 4.5:1, or #406006 for 7:1.

What is the complementary color of #aef32f?

#742FF3 sits directly opposite on the wheel. Softer options are the split-complements #2F4CF3 and #D62FF3, which give the same contrast with far less vibration.

What colors go well with #aef32f?

For interface work: #F8FAF4 as the surface, #DDEDC0 for borders, #7F9B4B for secondary text, #402BF7 as an accent and #517907 for hover and pressed states. For a palette, the analogous pair #F3D62F and #4CF32F stays calm, while #742FF3 is the loudest partner.

What is #aef32f in CMYK for printing?

cmyk(28%, 0%, 81%, 5%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #aef32f warm or cool?

Neutral — it scores 43 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F3F02F; nudged cooler, #65F52D.

Which Tailwind color is closest to #aef32f?

The lime family — its 500 step is #84cc16, ΔE2000 9.5 away. That is a visible difference, so define #aef32f as a custom token rather than reaching for the built-in.

How do I use #aef32f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#aef32f] or text-[#aef32f], 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 #aef32f with 50% opacity?

rgba(174, 243, 47, 0.5), or #aef32f80 in eight-digit hex. Over white that composites to #D7F997; over black, #577A18.

Is #aef32f a web-safe color?

No. The nearest web-safe colour is #99FF33, ΔE2000 4.1 away. The palette only matters for legacy displays and some email clients now.
