In the embodiment, the color difference data is stored on a line, and the viewing range is controlled by roles and data authority, so that the data transparency, timeliness and sharing are ensured. And the color difference report is generated by the system in time, whether the early warning condition is triggered or not is automatically judged, and the time point of finding the problem is advanced, so that the rectification cycle is shortened. Optionally, the color difference report can be displayed in a visual graph report form, the visual graph report form can be viewed in app and web, and any time node, any color matching point and any angle can be screened to generate the color difference report form through comparison.

For example, after the supplier receives the responsibility judgment problem, whether the paint raw material is abnormal or not can be automatically judged through data comparison, of course, whether the paint raw material has a problem or not can be determined through a self-checking mode and the like, and if the paint raw material with the abnormality is determined to be the self-problem, a temporary solution or a permanent solution can be provided; if the problem is not the problem of the supplier, the supplier can mention the complaint about the problem of the accountability, fill out the complaint reason and carry out secondary accountability by an accountability manager.
