How to automate the change of color for multiple part files?

Hi! I have 2000-4000 library part files . I want to have the ability to easily change the colors of these parts to red for example.

Changing the colors manually is not a solution ...

Do you have any suggestions how to automate this process? I have checked the task scheduler but there's no standard functionality to change colors of parts/assemblies.
