Recoloring art work

Abstract

A computer-implemented method alters component colors of art work associated with a drawing stroke on an electronic document. In one aspect, the invention generates a darkness value for each component color of each original color; generates a new color to substitute for each original color, the component color values of the new color being generated according to the corresponding darkness value and a reference color; and alters the component colors of the art work based on the new color values. In a second aspect, the invention provides a computer-implemented method for altering a component color of art work by mapping the component color to a new color based on a color space associated with the component color and applying the resulting color to components of the art work. In a third aspect, the computer-implemented method for altering component colors of the art work includes converting the color of components into a hue, saturations and brightness (HSB) color space; biasing hue values of a key color, a paint color, and a stroke color; mapping the hue values; transforming saturation and brightness values; unbiasing the hue values; converting the resulting color into original color space of the stroke color; and applying the resulting color to components of art work stroke derived from the components of the base art work.
