<p>A method for coloring a greyscale raster image defined by a plurality of predefined greyscale values, having the following steps: (i) receiving a color selection intended for a portion of the raster image; (ii) retrieving from a predefined database multiple groups of predefined color parameter values, each group of predefined color parameter values defining a color parameter associated with the selected color, and each group of predefined color parameter values including a predefined greyscale value; and (iii) for each pixel within said portion of said raster image, determining a pixel channel value for each of a plurality of color channels that collectively define an appearance of said pixel, said determination being based on said predefined greyscale value for said pixel, and said predefined color parameter values for at least two of said predefined color parameters associated with said selected color.</p> |
