[Closed] Simple Macroscript for changing materials

I’m new to all this scripting and to be honest I just heard about macro scripts. I’m looking for something like a Photoshop Action but don’t have an idea where to start.

I need to run several directoreis of similar files. It’s for a web configurator.
All the script has to do is to open a file, change color of object taken from the material library, change the render output path with “_color.png”, save the file. Open next file and so on…

It’s a bit time consuming to do it manually.
Can it be done with a script?
