At the present study, the fundamental color stimulus space (N*) obtained from the Cohen and Kappauf decomposition technique as an alternative to the measured spectral reflectance (N) was investigated. Based on the single-constant Kubelka-Munk theory, the (K/S)* space from the non-linear transformation of N* values was obtained and its consistency with (K/S) space taken from the measured reflectance was spectrally analyzed. The scalability for both spectral spaces was quantitatively evaluated in different concentrations through visible spectrum. The suitable wavelengths that (K/S)* still exhibit linear behavior with concentration variation were introduced. The obtained results showed that the non-linear transformation of fundamental color stimulus space, i.e. (K/S)* is more scalable. At the proposed wavelengths, the applicability limit of (K/S)* similar to the (K/S) is improved till the higher dye concentration and the obtained linearity for (K/S)* could be an proposed approach for the study of dyeing systems such as estimating the concentration from tristimulus values as colorimetry data.
