Abstract

A method is described for selective color correction of an original color image. In one embodiment, a color is selected by picking a colored pixel from the color image and a changed color, having a restricted color change, is associated with the selected color. All original colors, situated within a local color gamut, comprising the selected color, undergo a color modification according to the color change. The effect of the modification decreases as the original color reaches the boundary of the local color gamut. The selected color and changed color may be defined in the native color space, the local color gamut is preferentially defined by an action radius related to a psychometric color space. Two or more selective color corrections may be combined by a weighted mean modification, by choosing for each color change a weight value, which decreases as the selected color is more different from the original color.
