I sure wish this were possible. It's even worse in list view. I am used to working with lists of files and being able to find things at a glance from the color. The tiny ball is so far from the file name, it makes it practically useless for quick visual reference. I never realized how much I relied on those file names hilighted in colors until they vanished in Mavericks.
I wonder if anyone han hack the system to bring them back. They still show up in some file requesters, so that code is still in the system somewhere.
