"Green" refers to objects which disproportionately reflect or emit light of a wavelength between 520 and 570nm.

Am I missing something?

EDIT: Wait, you're talking about the mental experience of "seeing green". Never mind, I think.

No, he's talking about the property 'green', meaning that which all things we label as 'green' have in common. There is no unique physical property that these objects share. In fact, two objects which appear the exact same color can have vastly different reflectance profiles. It's called metamerism, and it's a function of our visual system being run off of opponent matches.
