Each building and landmark of central Amsterdam lights up under the pointer, takes the click colour when you select it and keeps a paint colour of its own.

• buildings.events and landmarks.events report the building or landmark under the pointer, its id and its properties. A handler is all it takes to turn the hover and click colours on.
• setBuildingColors and setLandmarkColors give the ones you name by id a colour of their own, which they keep as their tiles reload. The base map’s getBuildingIdAt names the building at a position, so two are coloured from coordinates.
• The hover and click knobs of Buildings3D set both colours, and the landmarks follow them.
