Abstract: A process for computing a dyeing or printing recipe corresponding to a given shade, whereina) a given shade in a FTa*b* colour space is defined, where FT is a depth of shade value which, irrespective of hue, defines points of equal colour strength which by definition lie in a plane of the FTa*b* colour space as defined, and a* and b* are values of the CIELab colour coordinate system,b) the FTa*b* colour space for each depth of shade plane is segmented into triangular levels by means of the a* and b* values of the dyes to be used for colour matching,c) in each defined depth of shade plane the given a* and b* values correspond to a specific ratio of the dyes of the suitable segment of the colour space, andd) the ratio of the dyes of the suitable segment is obtained by an iteration method.The process makes it possible to formulate dyeing and printing recipes accurately in accordance with a given reference shade.
