Method and apparatus for interactive color manipulation

A customized color transformation is generated in response to interactive user manipulation of source and target color gamuts. Data related to a first and to a second color gamut are loaded. An initial color transformation is selected. Based on this transformation, color transformation values are calculated, which are adapted for transforming a subset of values of the first color gamut into a corresponding subset of values of the second one. Visual representations of the first and the second color gamut and the calculated color transformation values are displayed in at least one display box of a user interface of a tool adapted for interactive color manipulation. The color transformation values are recalculated and the displayed visual representations are updated in response to a user manipulation applied to at least one of the visual representations of the first and of the second color gamut.
