How to use #64f360

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
  • Card and section backgrounds
  • 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
  • White 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 #0C7709
Safe as a 1px border on white
No — use #11AD0D

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 lightness keeps it airy and approachable.

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 #64f360 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.

#64f360, answered

What color is #64f360?

#64f360 is a light electric green, closest to Spring Green (ΔE2000 5.7). It sits at 118° on the hue wheel with 86% saturation and 67% lightness, which reads as cool.

What is the RGB value of #64f360?

rgb(100, 243, 96) — 100 red, 243 green and 96 blue out of 255, or 39.2% / 95.3% / 37.6% by channel.

What is #64f360 in HSL and HSV?

hsl(118, 86%, 67%) and hsv(118, 60%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #64f360 a light or a dark color?

It is a light color. Relative luminance is 0.6766 and perceived brightness is 77%, so black text on it reaches 14.53:1.

Should I use black or white text on #64f360?

Black. It scores 14.53:1 against #64f360, versus 1.45:1 for white — AAA at any size.

Is #64f360 accessible on a white background?

#64f360 on white scores 1.45:1, which fails WCAG AA at every size. Darken it to #0E870A to reach 4.5:1, or #0A6608 for 7:1.

What is the complementary color of #64f360?

#EF60F3 sits directly opposite on the wheel. Softer options are the split-complements #A660F3 and #F360AD, which give the same contrast with far less vibration.

What colors go well with #64f360?

For interface work: #F4FAF4 as the surface, #C1EDC0 for borders, #4D9B4B for secondary text, #CC5DF6 as an accent and #0C7709 for hover and pressed states. For a palette, the analogous pair #ADF360 and #60F3A6 stays calm, while #EF60F3 is the loudest partner.

What is #64f360 in CMYK for printing?

cmyk(59%, 0%, 61%, 5%). 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 #64f360 warm or cool?

Cool — it scores 62 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #9AF360; nudged cooler, #5EF592.

Which Tailwind color is closest to #64f360?

The lime family — its 500 step is #84cc16, ΔE2000 11.6 away. That is a visible difference, so define #64f360 as a custom token rather than reaching for the built-in.

How do I use #64f360 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#64f360] or text-[#64f360], 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 #64f360 with 50% opacity?
