This invention describes methods and systems to efficiently map and extract information from digital representations of buildings for use for a variety of purposes, including but not limited to the performance of dynamic simulations of building performance, and for codes and standards compliance. The method includes successively subjecting a plurality of filter layers differing in color from each other to a patterning process to form the plurality of color filter patterns. A source of content advisory rating information corresponding to said television program is provided. The drivers may be driven, for example, by pulse-modulated signals specifying average currents for the groups of LEDs.
