How to use #39eb70

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 #0C742C
Safe as a 1px border on white
No — use #11A840

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.

#39eb70, answered

What color is #39eb70?

#39eb70 is a balanced electric green, closest to Spring Green (ΔE2000 4.3). It sits at 139° on the hue wheel with 82% saturation and 57% lightness, which reads as cool.

What is the RGB value of #39eb70?

rgb(57, 235, 112) — 57 red, 235 green and 112 blue out of 255, or 22.4% / 92.2% / 43.9% by channel.

What is #39eb70 in HSL and HSV?

hsl(139, 82%, 57%) and hsv(139, 76%, 92%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #39eb70 a light or a dark color?

It is a light color. Relative luminance is 0.6146 and perceived brightness is 73%, so black text on it reaches 13.29:1.

Should I use black or white text on #39eb70?

Black. It scores 13.29:1 against #39eb70, versus 1.58:1 for white — AAA at any size.

Is #39eb70 accessible on a white background?

#39eb70 on white scores 1.58:1, which fails WCAG AA at every size. Darken it to #0E8833 to reach 4.5:1, or #0A6727 for 7:1.

What is the complementary color of #39eb70?

#EB39B4 sits directly opposite on the wheel. Softer options are the split-complements #C939EB and #EB395B, which give the same contrast with far less vibration.

What colors go well with #39eb70?

For interface work: #F4FAF6 as the surface, #C0EDCE for borders, #4B9B63 for secondary text, #EF35E5 as an accent and #0C742C for hover and pressed states. For a palette, the analogous pair #5BEB39 and #39EBC9 stays calm, while #EB39B4 is the loudest partner.

What is #39eb70 in CMYK for printing?

cmyk(76%, 0%, 52%, 8%). 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 #39eb70 warm or cool?

Cool — it scores 70 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #44EB39; nudged cooler, #37EDB2.

Which Tailwind color is closest to #39eb70?

The green family — its 500 step is #22c55e, ΔE2000 9.2 away. That is a visible difference, so define #39eb70 as a custom token rather than reaching for the built-in.

How do I use #39eb70 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#39eb70] or text-[#39eb70], 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 #39eb70 with 50% opacity?

rgba(57, 235, 112, 0.5), or #39eb7080 in eight-digit hex. Over white that composites to #9CF5B8; over black, #1D7638.

Is #39eb70 a web-safe color?
