The present paper aims to investigate the influence of image gamuts on cross–media colour image reproduction by creating a set of images that have this image characteristic perturbed in a known way. This is done using the following two approaches: First, by selecting a single image and obtaining variations of it which have different colour gamuts. Second, by creating a pair of image sets whereby the images in the first set differ in colour gamut and the images of the second set are transformations of the first set of images so that all the images have the same gamut. Reproducing these images using a range of gamut mapping algorithms (GMAs), it can be seen whether variations in gamut and the difference between multi– and equi–gamut sets result in difference of performance. The results of these experiments then show that image gamuts have no significant effect on colour gamut mapping.
