Based on the idea of the spectral visual response fitting, the visual difference between the spectral reflectance factor function of the standard and specimen was proposed in this paper. Basic equations used in the recipe formulation as well as recipe correction were derived based on the spectral visual response fitting in matrix form and an algorithm for the least‐squares match has been developed. The iterative procedure for the recipe correction has been established in this algorithm. Twenty standards were used in our numerical experiments. The experimental results showed that the average colour difference against for the standards under the five different illuminants (D65, A, F1, F2 and F3) was smaller than one based on other spectrophotometric fittings, balanced the colour differences better and produced lower metamerism.
