A color data conversion method involves generating second color data (83, 86, 89) included in a second gamut (2) of a second color picture device from first color data (81, 84, 87) included in a first gamut of a first color picture device. It comprises the following steps:
calculating third color data (82, 85, 88) included in the second gamut and derived from the saturation value of the first color data; and
converting the first color data to the second color data by interpolating the first color data toward the third color data in such a way that the second color data is included in the second gamut;
wherein the step of calculating the third color data (82, 85, 88) further comprises the steps of:
calculating fifth color data (90) with the highest saturation of color data included in the second gamut in the same hue as the first color data; and
calculating the third color data on a straight line connecting sixth color data (91), being an achromatic color, and the fifth color data (90).
