ABSTRACT:
Methods and apparatus, including computer program products, implement techniques for configuring at least a portion of a document for display in a display environment. The techniques include generating a document color palette for all or a portion of an electronic document, where the colors of the document color palette are selected based on colors of a plurality of color containing objects in the document or portion thereof, and generating a plurality of views of the document, two or more of the views being based on different color palettes. The plurality of views includes a document view including each of the plurality of color containing objects, where each color containing object in the document view is represented using the document color palette.
