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 #5ace47

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 #25651B
Safe as a 1px border on white
No — use #3FAA2D

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 #5ace47 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.

#5ace47, answered

What color is #5ace47?

#5ace47 is a balanced vivid green, closest to Lime Green (ΔE2000 2.6). It sits at 112° on the hue wheel with 58% saturation and 54% lightness, which reads as cool.

What is the RGB value of #5ace47?

rgb(90, 206, 71) — 90 red, 206 green and 71 blue out of 255, or 35.3% / 80.8% / 27.8% by channel.

What is #5ace47 in HSL and HSV?

hsl(112, 58%, 54%) and hsv(112, 66%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #5ace47 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4677 and perceived brightness is 66%, so black text on it reaches 10.35:1.

Should I use black or white text on #5ace47?

Black. It scores 10.35:1 against #5ace47, versus 2.03:1 for white — AAA at any size.

Is #5ace47 accessible on a white background?

#5ace47 on white scores 2.03:1, which fails WCAG AA at every size. Darken it to #328624 to reach 4.5:1, or #26661B for 7:1.

What is the complementary color of #5ace47?

#BB47CE sits directly opposite on the wheel. Softer options are the split-complements #7847CE and #CE479D, which give the same contrast with far less vibration.

What colors go well with #5ace47?

For interface work: #F5FAF4 as the surface, #C6EDC0 for borders, #569B4B for secondary text, #9A42D3 as an accent and #25651B for hover and pressed states. For a palette, the analogous pair #9DCE47 and #47CE78 stays calm, while #BB47CE is the loudest partner.

What is #5ace47 in CMYK for printing?

cmyk(56%, 0%, 66%, 19%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #5ace47 warm or cool?

Cool — it scores 59 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8BCE47; nudged cooler, #45D064.

Which Tailwind color is closest to #5ace47?

The green family — its 500 step is #22c55e, ΔE2000 6.4 away. That is a visible difference, so define #5ace47 as a custom token rather than reaching for the built-in.

How do I use #5ace47 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#5ace47] or text-[#5ace47], 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 #5ace47 with 50% opacity?

rgba(90, 206, 71, 0.5), or #5ace4780 in eight-digit hex. Over white that composites to #ADE7A3; over black, #2D6724.

Is #5ace47 a web-safe color?

No. The nearest web-safe colour is #66CC33, ΔE2000 2.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #5ace47 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 #5ace47?

The safest is same-hue elevation: linear-gradient(135deg, #85DB77, #5ace47 45%, #25651B). For more colour, a short hue run to #34C28B keeps it rich without turning muddy.
