#7EFF00a vivid green

At a glance#7EFF00, oklch(89.0% 0.265 136.1), is a vivid green, a near match for chartreuse #7FFF00 or Radium #7FFF00, fully saturated at the sRGB gamut edge for its hue. Its hue sits mid-wheel, neither warm nor cool. Pair it with a cool vivid indigo #4F43CF as an accent, a warm light gold #F0CF6D for harmony, and a pastel teal #C1CCBC as a neutral. Try it as a screen-first brand or accent color, and it takes black text at AA contrast. It shifts further on press than a run can hold, though, so Rhapsody would keep it off print-led brand work.

Color family

What kind of green is #7EFF00?

Every color has a place in the standard vocabulary. This is #7EFF00's, measured rather than asserted.

#7EFF00's Munsell numbers: hue 8.4GY, value 8.9 (how light), chroma 16.2 (how vivid). That places it in ISCC-NBS block vivid yellowish green, one of 267 named ranges the standard sorts every color into. Chroma 16.2 is about as saturated as named colors get. Nothing muted shares this block.

It reaches 100% of the way to the edge of your screen's gamut (the palette a screen can actually show) for this hue. That's as saturated as #7EFF00 gets and still shows up on a normal screen. It's also why no press can reproduce it unchanged, which the print section below explains. Same cause, both effects.
