ABSTRACT:
A method for generating a color palette from elements having multiple color component values including the steps of determining a color proximity of the elements by organizing the elements by a most significant bit of each element color component value followed by less significant bits of each element color component value, partitioning the organized elements into multiple groups by the color proximity, generating a color palette from the multiple groups, and displaying the generated color palette. In addition, an apparatus for generating a color palette from elements having multiple color component values including an apparatus for determining a color proximity of the elements by organizing the elements by a most significant bit of each element color component value followed by less significant bits of each element color component value, an apparatus for partitioning the organized elements into multiple groups by the color proximity, an apparatus for generating a color palette from the multiple groups, and a display for displaying the generated color palette.
