“Green background” is not a photography term for vibration reduction or image stabilization. In that context, it refers to the formatting of the Wikipedia table: lenses with stabilization are highlighted with a green-colored background in the list.

So the useful part of the statement is simply that VR/OS/VC are optical image stabilization systems used to reduce blur from camera movement. The “green background” wording is just a poorly written note about how those lenses are marked in the table, not a lens feature.
