Find Colour-coded files

In my audiobook library, I try to change the font colour of the book title to red (to represent I've read the book).

Is there any way to list the folders that have been changed to red?

Please take into account that I'm more 'Bill' from 'Bill and Ben' than Bill Gates, so any coding will have to be step by step (baby steps if possible) for me to have a chance in getting it to work.

All help will be appreciated.

You can use Tools > Find Files > Advanced to search for files by label (e.g. "Red" or, in the screenshot below, "Highlight"):
