摘要

A method of converting a first colour value as determined by first colour co-ordinates in a colour space defined by colour parameters, said first colour co-ordinates being situated outside a boundary of a predetermined colour range situated in the colour space, to a second colour value determined by second colour co-ordinates in the colour space, said second colour co-ordinates being situated on said boundary of said colour range. To this end, the method comprises determining, in dependence on the distance of the first colour co-ordinates from the boundary, an extended part of the boundary of the colour range and establishing the second colour co-ordinates on the basis of said extended part of the boundary. In one embodiment, the extended part of the boundary is determined by the part situated between a first and second distance range from the first colour co-ordinates and the second colour co-ordinates are determined by the average of the colour co-ordinates situated in that part of the boundary.
