How to use #32e721

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 #15730C
Safe as a 1px border on white
No — use #1FA912

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.

#32e721, answered

What color is #32e721?

#32e721 is a balanced electric green, closest to Lime (ΔE2000 5.2). It sits at 115° on the hue wheel with 81% saturation and 52% lightness, which reads as cool.

What is the RGB value of #32e721?

rgb(50, 231, 33) — 50 red, 231 green and 33 blue out of 255, or 19.6% / 90.6% / 12.9% by channel.

What is #32e721 in HSL and HSV?

hsl(115, 81%, 52%) and hsv(115, 86%, 91%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #32e721 a light or a dark color?

It is a light color. Relative luminance is 0.5794 and perceived brightness is 70%, so black text on it reaches 12.59:1.

Should I use black or white text on #32e721?

Black. It scores 12.59:1 against #32e721, versus 1.67:1 for white — AAA at any size.

Is #32e721 accessible on a white background?

#32e721 on white scores 1.67:1, which fails WCAG AA at every size. Darken it to #19890F to reach 4.5:1, or #13640B for 7:1.

What is the complementary color of #32e721?

#D621E7 sits directly opposite on the wheel. Softer options are the split-complements #7321E7 and #E72195, which give the same contrast with far less vibration.

What colors go well with #32e721?

For interface work: #F5FAF4 as the surface, #C4EDC0 for borders, #529B4B for secondary text, #A61CEC as an accent and #15730C for hover and pressed states. For a palette, the analogous pair #95E721 and #21E773 stays calm, while #D621E7 is the loudest partner.

What is #32e721 in CMYK for printing?

cmyk(78%, 0%, 86%, 9%). 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 #32e721 warm or cool?

Cool — it scores 60 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7BE721; nudged cooler, #1FE957.

Which Tailwind color is closest to #32e721?

The lime family — its 500 step is #84cc16, ΔE2000 9.3 away. That is a visible difference, so define #32e721 as a custom token rather than reaching for the built-in.

How do I use #32e721 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#32e721] or text-[#32e721], 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 #32e721 with 50% opacity?
