1. A system implementable on a computing device for handling color assignment within a complex document, the system comprising: a user interface to facilitate user modification of at least one first color to at least one second color within a previously chosen color scheme for a component of said document, said color scheme having a predetermined number X of principal colors and a predetermined number Y of associated subordinate colors per principal color; a color handler to modify said color scheme to produce an updated color scheme to match a perceived brightness of said at least one second color throughout at least a portion of said updated color scheme; a color processor to process and apply said updated color scheme at least to said component; and an inheritance processor to implement said modifications according to at least one pre-defined inheritance relationship between said component and at least one other component; wherein said color handler comprises a brightness handler to calculate said perceived brightness of said second color; and wherein said brightness handler comprises a searcher to search through a perceived brightness graph to find the color parameters required to generate said perceived brightness.
