Recently this question has come up quite a bit in the help forums and I wanted to share an easy work-around. One of the beauties for using Google Drive and Docs is the benefit for sharing files and folders digitally. Printing of files is less often used and creating with color is no longer a budgetary concern. This opens doors to other ways of categorizing and organizing ones files.
If a user changes the background of a Google Doc, Slide, Sheet, Drawings or Forms it is easily spotted from within a folder. This means you can have several groups of colleagues or students collaborating within the same folder on different documents focused on specific content. You can further tweak this method by adding numbers within the doc’s name to represent each color group. An example of this would be to use “00” for representing blue and “01” to represent the yellow group. This method for file organization will work both within Team Drive and Google Drive.
