Can the title of a document, image or any sort of file be more colors than just white?

I want them to be red, pink, green, yellow, orange, brown, blue and so on.

The reason is that I save articles in goodnotes and then I use them as sources in my papers. To make writing the sources quicker i just assort them into colors as to immeditaly tell them apart. However I would be much more effecient if I had some help to remember which color belongs to which goodnotes files - the solution is if the title were different colors. I would also be able to tell them apart when I have multiple tabs open, without having to read the name.

I can use emojis for this reason, but im suggesting it anyways
