I too am a fan of the new Google Maps colour scheme -- and it's very interesting that they've gone for a similar scheme to the new (ish) OSM scheme! I've always thought of "landuse" as being equivalent to Google's beige "high activity" areas -- particularly "landuse=retail" to highlight town centres and retail parks. (I'm also a fan of "landuse=residential" polygons to highlight built-up areas, though I know some OSM-ers disagree.) So IMO, OSM already has the ability to match Google in this regard -- but using polygons rather than algorithms.
