What kind of green is Grass Green?

Every color has a place in the standard vocabulary. This is Grass Green's, measured rather than asserted.

Grass Green's Munsell numbers: hue 8.4GY, value 5.5 (how light), chroma 11.7 (how vivid). That places it in ISCC-NBS block vivid yellowish green, one of 267 named ranges the standard sorts every color into. Chroma 11.7 is moderate. Clearly colored, but not so saturated it fights the colors around it.

There's still some room before it hits the edge of what your screen can show for this hue. It could go a little more saturated and stay in gamut.
