ABSTRACT:
A system and method for managing the color palette for an object oriented operating system providing for the sharing of a plurality (e.g., 256) of colors for display by an external device. In a first aspect, an 8-bit color lookup table (CLUT) is shared by a plurality of views in a document being displayed on the external device such that consistent looking color is provided across a plurality of graphic devices. The inventive method includes creating a color look up table (CLUT) for the operating system, uniformly dividing the CLUT into a predetermined number of colors, displaying graphic information having a plurality of views, and sharing the predetermined number of colors in the CLUT amongst the plurality of views of the graphic information. The predetermined number of colors includes a plurality of colors each of which have a predetermined consistency when shared between first and second views of the plurality of views.
