Calling it with two arguments folder1 and folder2, it walks the first folder and for each file searches a corresponding file in the second folder. If it is found, the relative path is printed in green, if they have different modified time or size, it is printed in yellow, and if it is not found then it is printed in red.

In practice if you just want to know whether the folders are the same, then Chris' script is better. If you want to know what's missing or different from one folder to another, then my script will tell you.
NOTE: you will need termcolor installed, pip install termcolor.
