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 #5eb58c

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #285741
Safe as a 1px border on white
No — use #4BA47A

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. 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 #5eb58c 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.

#5eb58c, answered

What color is #5eb58c?

#5eb58c is a balanced soft green, closest to Medium Sea Green (ΔE2000 6.2). It sits at 152° on the hue wheel with 37% saturation and 54% lightness, which reads as cool.

What is the RGB value of #5eb58c?

rgb(94, 181, 140) — 94 red, 181 green and 140 blue out of 255, or 36.9% / 71% / 54.9% by channel.

What is #5eb58c in HSL and HSV?

hsl(152, 37%, 54%) and hsv(152, 48%, 71%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #5eb58c a light or a dark color?

It is a mid-tone. Relative luminance is 0.3732 and perceived brightness is 61%, so black text on it reaches 8.46:1.

Should I use black or white text on #5eb58c?

Black. It scores 8.46:1 against #5eb58c, versus 2.48:1 for white — AAA at any size.

Is #5eb58c accessible on a white background?

#5eb58c on white scores 2.48:1, which fails WCAG AA at every size. Darken it to #3B8160 to reach 4.5:1, or #2D6149 for 7:1.

What is the complementary color of #5eb58c?

#B55E87 sits directly opposite on the wheel. Softer options are the split-complements #B55EB2 and #B5605E, which give the same contrast with far less vibration.

What colors go well with #5eb58c?

For interface work: #F5FAF8 as the surface, #C7E5D7 for borders, #4B9B75 for secondary text, #BA599F as an accent and #285741 for hover and pressed states. For a palette, the analogous pair #5EB560 and #5EB2B5 stays calm, while #B55E87 is the loudest partner.

What is #5eb58c in CMYK for printing?

cmyk(48%, 0%, 23%, 29%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #5eb58c warm or cool?

Cool — it scores 76 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #5EB56C; nudged cooler, #5CB7AE.

Which Tailwind color is closest to #5eb58c?

The emerald family — its 500 step is #10b981, ΔE2000 5.5 away. That is a visible difference, so define #5eb58c as a custom token rather than reaching for the built-in.

How do I use #5eb58c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#5eb58c] or text-[#5eb58c], 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 #5eb58c with 50% opacity?

rgba(94, 181, 140, 0.5), or #5eb58c80 in eight-digit hex. Over white that composites to #AFDAC6; over black, #2F5B46.

Is #5eb58c a web-safe color?

No. The nearest web-safe colour is #66CC99, ΔE2000 6.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #5eb58c mean?
