Objective To enable Apple monitor to accurately display the input color information and predict the output color effects, we explored the influence of two kinds of standard light source parameters on the color display performance of Apple computer. Methods Firstly, color profiles of Apple monitor under D50 and D65 light source parameters were made and used. Then Eyeone Pro spectrophotometer and Measuretool software were used to compare and analyze the color display performance of color patches after using the above profiles, and finally CHROMiX ColorThink software was used to generate two color spaces and show Lab values of whitepoints according to the profiles. Results Average color difference of color patches was 7. 09 with most of the gray patches less than 1,while some blue and magenta patches had much higher difference, ranging from 6. 38 to 40. 63. From the corresponding color spaces obtained, we concluded that the color of whitepoint under D65 light source parameters was bluer than that under D50 light source parameters. Conclusion Monitor display effects of color patches were closely linked with the properties of D50 and D65 light sources.
