    • A method for making a dye mixture to produce a target colour on a given substrate, comprising the steps of: −a) measuring reflectance values RT(λi) of the target colour at a plurality of wavelengths λi=1, 2 . . . n; b) measuring reflectance values Rs (λi) of the substrate at the same wavelengths λi; forming a set of concentrations cj of M dyes in the calculated concentrations; the database having been compiled by aa) making dyeings of combinations of the dyes Dn at different concentrations; bb) measuring the reflectance values R of the dyeings at different wavelengths; cc) defining a function f(R); dd) defining a relationship between f(R) and c involving constants g and k; and ee) for each dye Dn determining constants gn, kn, such that the calculated values for f(R), c, gn kn approximate closely the measured values.
