ok after a bit more experimentation, here is what I set ... set all the colors to gray (or whatever color you want the floor plans to be) in the first style, and then recolor everything you need into the following styles. This causes floor plans to display as a single color block.
var styles = [ { featureType: "all", stylers: [ { color: "#505050" } ] }, { featureType: "road", elementType: "geometry", stylers: [ { visibility: "simplified" }, { color: '#505050' } ] }, { featureType: "all", elementType: "labels", stylers: [ { visibility: "off" } ] }, { featureType: "administrative", stylers: [ { visibility: "off" } ] }, { featureType: "transit", stylers: [ { visibility: "off" } ] }, { featureType: "poi", stylers: [ { visibility: "off" } ] }, { featureType: "landscape", stylers: [ { color: '#FF0000' } ] }, { featureType: "landscape.man_made", stylers: [ { color: '#393939' } ] }, { featureType: "landscape.natural", stylers: [ { color: '#393939' } ] }, { featureType: "water", stylers: [ { color: '#252525' } ] } ];
