Its explained on Hatsune Miku Append.

Light and Vivid are the "high" and "mid" power type appends and the foils to "dark" and "sweet", "Vivid"'s role was to be a bridge between "light" and "solid".

However, they ARE the closet sounding Appends and its kinda why their the ones chosen to be the bonus or "sold separately" vocals in the end.
