How to use #3ab511

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 #25750B
Safe as a 1px border on white
No — use #35A710

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 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.

Transparency

What each alpha value actually composites to. The top row is #3ab511 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.

#3ab511, answered

What color is #3ab511?

#3ab511 is a dark electric green, closest to Lime Green (ΔE2000 6.5). It sits at 105° on the hue wheel with 83% saturation and 39% lightness, which reads as neutral.

What is the RGB value of #3ab511?

rgb(58, 181, 17) — 58 red, 181 green and 17 blue out of 255, or 22.7% / 71% / 6.7% by channel.

What is #3ab511 in HSL and HSV?

hsl(105, 83%, 39%) and hsv(105, 91%, 71%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #3ab511 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3399 and perceived brightness is 56%, so black text on it reaches 7.80:1.

Should I use black or white text on #3ab511?

Black. It scores 7.80:1 against #3ab511, versus 2.69:1 for white — AAA at any size.

Is #3ab511 accessible on a white background?

#3ab511 on white scores 2.69:1, which fails WCAG AA at every size. Darken it to #2B860D to reach 4.5:1, or #21660A for 7:1.

What is the complementary color of #3ab511?

#8C11B5 sits directly opposite on the wheel. Softer options are the split-complements #3A11B5 and #B5118C, which give the same contrast with far less vibration.

What colors go well with #3ab511?

For interface work: #F6FAF4 as the surface, #CBEDC0 for borders, #5F9B4B for secondary text, #630DB9 as an accent and #25750B for hover and pressed states. For a palette, the analogous pair #8CB511 and #11B53A stays calm, while #8C11B5 is the loudest partner.

What is #3ab511 in CMYK for printing?

cmyk(68%, 0%, 91%, 29%). 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 #3ab511 warm or cool?

Neutral — it scores 56 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #76B511; nudged cooler, #0FB723.

Which Tailwind color is closest to #3ab511?

The green family — its 500 step is #22c55e, ΔE2000 8.6 away. That is a visible difference, so define #3ab511 as a custom token rather than reaching for the built-in.

How do I use #3ab511 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#3ab511] or text-[#3ab511], 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 #3ab511 with 50% opacity?

rgba(58, 181, 17, 0.5), or #3ab51180 in eight-digit hex. Over white that composites to #9DDA88; over black, #1D5B09.

Is #3ab511 a web-safe color?

No. The nearest web-safe colour is #33CC00, ΔE2000 6.1 away. The palette only matters for legacy displays and some email clients now.
