Abstract
A system for handling color assignment within a complex document includes 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 the document, the color scheme having a principal colors and a of associated subordinate colors per principal color displayed as a matrix, a color handler to update the previously chosen color scheme color scheme to produce an updated color scheme matching a perceived brightness of the at least one second color, the color handler including a unifier to calculate an average perceived brightness for all cells in a row within the matrix and to change the lightness value for each cell while keeping the same hue and saturation to ensure that all cells within the row have the same perceived brightness, and a color processor to apply the updated color scheme.
