Pavement markings having a substrate with a first major surface and a second major surface; and a plurality of retroref lective elements (100) disposed along the first major surface of the substrate, the retroref lective elements each having a solid spherical core (110) and at least a first complete concentric optical interference layer (120) overlying core. In some embodiments, the retroref lective elements of the pavement marking further include a second complete concentric optical interference layer overlying the first complete concentric optical interference layer. In still other embodiments, the retroref lective elements of the pavement markings further include a third complete concentric optical interference layer overlying the second complete concentric optical interference layer.
