Abstract
The disclosed system and method allow an artist to blend a desired color from available source (i.e., menu) colors and use the resulting blend color at the desired part of the picture and/or store the blend color for future use as a source color. A palette mixing area and a menu of colors can be displayed on a video screen. A signal defining a selected source color is generated when the artist touches with a stylus an area on a touch tablet which corresponds to the screen display of the selected color. When the stylus then touches the part of the touch tablet corresponding to a selected part of the palette mixing area on the screen, the screen shows at that selected area a blend of any color preexisting there and the selected color. A signal defining the blend color can be stored for future use as a source color. The proportions of the two colors in a blend can be controlled by stylus pressure, number of overstrokes and/or stylus dwell time.
