How to use #5ce581

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 #126E2A
Safe as a 1px border on white
No — use #1BAB42

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 #5ce581 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.

#5ce581, answered

What color is #5ce581?

#5ce581 is a balanced vivid green, closest to Light Green (ΔE2000 4.9). It sits at 136° on the hue wheel with 73% saturation and 63% lightness, which reads as cool.

What is the RGB value of #5ce581?

rgb(92, 229, 129) — 92 red, 229 green and 129 blue out of 255, or 36.1% / 89.8% / 50.6% by channel.

What is #5ce581 in HSL and HSV?

hsl(136, 73%, 63%) and hsv(136, 60%, 90%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #5ce581 a light or a dark color?

It is a light color. Relative luminance is 0.5990 and perceived brightness is 74%, so black text on it reaches 12.98:1.

Should I use black or white text on #5ce581?

Black. It scores 12.98:1 against #5ce581, versus 1.62:1 for white — AAA at any size.

Is #5ce581 accessible on a white background?

#5ce581 on white scores 1.62:1, which fails WCAG AA at every size. Darken it to #168835 to reach 4.5:1, or #106527 for 7:1.

What is the complementary color of #5ce581?

#E55CC0 sits directly opposite on the wheel. Softer options are the split-complements #C55CE5 and #E55C7B, which give the same contrast with far less vibration.

What colors go well with #5ce581?

For interface work: #F4FAF6 as the surface, #C0EDCC for borders, #4B9B60 for secondary text, #B418B1 as an accent and #126E2A for hover and pressed states. For a palette, the analogous pair #7BE55C and #5CE5C5 stays calm, while #E55CC0 is the loudest partner.

What is #5ce581 in CMYK for printing?

cmyk(60%, 0%, 44%, 10%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #5ce581 warm or cool?

Cool — it scores 69 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #69E55C; nudged cooler, #5AE7B4.

Which Tailwind color is closest to #5ce581?

The green family — its 500 step is #22c55e, ΔE2000 8.4 away. That is a visible difference, so define #5ce581 as a custom token rather than reaching for the built-in.

How do I use #5ce581 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#5ce581] or text-[#5ce581], 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 #5ce581 with 50% opacity?

rgba(92, 229, 129, 0.5), or #5ce58180 in eight-digit hex. Over white that composites to #AEF2C0; over black, #2E7341.

Is #5ce581 a web-safe color?

No. The nearest web-safe colour is #66CC99, ΔE2000 9.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #5ce581 mean?
