Evaluation method for the color preference of lighting traditional Chinese paintings in museum based on light source spectral analysis

To evaluate the lighting color preference on traditional Chinese paintings based on the spectral power distributions (SPDs) of light sources, an experiment to examine the color preference of 40 representative SPDs illuminating two typical traditional Chinese paintings was performed in a 1:1 simulated exhibition hall. By decomposing the data, the influence trend from the different narrowband spectra on the color preference was obtained, and two key spectra with a significant influence on the color preference were determined (WLP = 425 nm with FWHM = 20 nm and WLP = 525 nm with FWHM = 30 nm). With an evaluation model using the relative spectral areas of S
