How to use #1eb52f

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
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • 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 #126D1C
Safe as a 1px border on white
No — use #1DAC2D

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 low lightness adds weight and formality.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

What each alpha value actually composites to. The top row is #1eb52f 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.

#1eb52f, answered

What color is #1eb52f?

#1eb52f is a dark vivid green, closest to Lime Green (ΔE2000 6.6). It sits at 127° on the hue wheel with 72% saturation and 41% lightness, which reads as cool.

What is the RGB value of #1eb52f?

rgb(30, 181, 47) — 30 red, 181 green and 47 blue out of 255, or 11.8% / 71% / 18.4% by channel.

What is #1eb52f in HSL and HSV?

hsl(127, 72%, 41%) and hsv(127, 83%, 71%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #1eb52f a light or a dark color?

It is a mid-tone. Relative luminance is 0.3353 and perceived brightness is 55%, so black text on it reaches 7.71:1.

Should I use black or white text on #1eb52f?

Black. It scores 7.71:1 against #1eb52f, versus 2.73:1 for white — AAA at any size.

Is #1eb52f accessible on a white background?

#1eb52f on white scores 2.73:1, which fails WCAG AA at every size. Darken it to #178924 to reach 4.5:1, or #11661B for 7:1.

What is the complementary color of #1eb52f?

#B51EA4 sits directly opposite on the wheel. Softer options are the split-complements #7B1EB5 and #B51E58, which give the same contrast with far less vibration.

What colors go well with #1eb52f?

For interface work: #F4FAF5 as the surface, #C0EDC5 for borders, #4B9B54 for secondary text, #A41AB9 as an accent and #126D1C for hover and pressed states. For a palette, the analogous pair #58B51E and #1EB57B stays calm, while #B51EA4 is the loudest partner.

What is #1eb52f in CMYK for printing?

cmyk(83%, 0%, 74%, 29%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #1eb52f warm or cool?

Cool — it scores 65 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #44B51E; nudged cooler, #1CB766.

Which Tailwind color is closest to #1eb52f?

The green family — its 500 step is #22c55e, ΔE2000 6.4 away. That is a visible difference, so define #1eb52f as a custom token rather than reaching for the built-in.

How do I use #1eb52f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#1eb52f] or text-[#1eb52f], 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 #1eb52f with 50% opacity?

rgba(30, 181, 47, 0.5), or #1eb52f80 in eight-digit hex. Over white that composites to #8FDA97; over black, #0F5B18.

Is #1eb52f a web-safe color?

No. The nearest web-safe colour is #33CC33, ΔE2000 6.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #1eb52f mean?
