How to use #36bc13

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 #21740C
Safe as a 1px border on white
No — use #31A911

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.

#36bc13, answered

What color is #36bc13?

#36bc13 is a dark electric green, closest to Lime Green (ΔE2000 4.6). It sits at 108° on the hue wheel with 82% saturation and 41% lightness, which reads as neutral.

What is the RGB value of #36bc13?

rgb(54, 188, 19) — 54 red, 188 green and 19 blue out of 255, or 21.2% / 73.7% / 7.5% by channel.

What is #36bc13 in HSL and HSV?

hsl(108, 82%, 41%) and hsv(108, 90%, 74%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #36bc13 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3680 and perceived brightness is 58%, so black text on it reaches 8.36:1.

Should I use black or white text on #36bc13?

Black. It scores 8.36:1 against #36bc13, versus 2.51:1 for white — AAA at any size.

Is #36bc13 accessible on a white background?

#36bc13 on white scores 2.51:1, which fails WCAG AA at every size. Darken it to #27890E to reach 4.5:1, or #1D640A for 7:1.

What is the complementary color of #36bc13?

#9913BC sits directly opposite on the wheel. Softer options are the split-complements #4513BC and #BC138A, which give the same contrast with far less vibration.

What colors go well with #36bc13?

For interface work: #F6FAF4 as the surface, #C9EDC0 for borders, #5B9B4B for secondary text, #6F0FC0 as an accent and #21740C for hover and pressed states. For a palette, the analogous pair #8ABC13 and #13BC45 stays calm, while #9913BC is the loudest partner.

What is #36bc13 in CMYK for printing?

cmyk(71%, 0%, 90%, 26%). 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 #36bc13 warm or cool?

Neutral — it scores 57 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #74BC13; nudged cooler, #11BE2D.

Which Tailwind color is closest to #36bc13?

The green family — its 500 step is #22c55e, ΔE2000 7.9 away. That is a visible difference, so define #36bc13 as a custom token rather than reaching for the built-in.

How do I use #36bc13 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#36bc13] or text-[#36bc13], 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 #36bc13 with 50% opacity?

rgba(54, 188, 19, 0.5), or #36bc1380 in eight-digit hex. Over white that composites to #9BDE89; over black, #1B5E0A.

Is #36bc13 a web-safe color?

No. The nearest web-safe colour is #33CC00, ΔE2000 4.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #36bc13 mean?
