The pigments in museum collection paintings are highly sensitive to light,making their colors prone to damage and in urgent need of protection. However,current exhibition lighting has not fully taken into account the impact of relative humidity on photochemical reactions. Additionally,some museum artifacts have already adapted to the existing environment,which exhibits significant variations in relative humidity. Therefore,targeted lighting design is necessary to address these issues. Therefore,it is essential to study the color damage patterns under different relative humidity conditions and light source illuminance levels. This study used a D55 light source and conducted lighting aging experiments under four relative humidity conditions (20％,40％,60％,80％) and five illuminance levels (0 lx,50 lx,100 lx,200 lx,300 lx) for five different pigments. Each cycle lasted 60 h,with a total of ten cycles. The color coordinates were measured,and color difference values were calculated. The results reveal the color damage patterns of different pigments under the coupling effects of light and humidity. Specifically,the degree of color damage is highest under high humidity and high illuminance conditions,and lowest under medium humidity and low illuminance conditions. Additionally,yellow and russet pigments are more susceptible to the combined effects of light and humidity. This research provides a basis for the future design of exhibition lighting for museum collection paintings.
