The work aims to increase the stability of color reproduction of high-simulation artworks and improve de-fects caused by metamerism in chroma replication so as to propose a color correction model. Y-N model was selected for improvement based on traditional color reproduction model. The YNSN model was used for optimization to obtain accurate yule-nielson correction coefficients. Then, the RMS error of the spectrum and the fitting were selected as the controlled variables. According to the minimum RMS error of the spectrum and the highest degree of fitting, the optimal value of n was selected to improve the accuracy of the reproduction color. The experimental results showed that the final linear correction values of n were: C 2.7814, M 2.9312, Y 3.9621 and K 5.0116, the average RMS of the spectrum reached 0.0265, and the average degree of fit was 0.9972. The model can effectively correct the color reproduction of the artwork and has high color correction accuracy.
