AbstractA method and apparatus for electronically retouching an image are described. The apparatus comprises a source (1) of color component image signals representing the color component values for the picture elements of the image to enable the image to be displayed on a monitor screen (8). A source (9) of color data is provided representing the color component values of a first range of colors, adjacent colors differing from each other by more than a predetermined amount. A control device (2) such as a minicomputer causes the monitor screen (8) to display the first range of colors. Operator-control apparatus (3) such as a digitizing table enables the operator to select one of the displayed colors, whereby the control device (2) thereupon causes the monitor screen (8) to display a second range of colors centered on the selected color, adjacent colors of the second range differing from each other by less than the predetermined amount, the operator-control apparatus (3) enabling the operator to select one of the second range of colors. A store (10) is provided for storing data representing the color component values of the selected one of the second range of colors.
