Colored editor tab enhancement suggestion

I am often working (in Netbeans 5.0) with multiple projects open. And
some some files between projects have the same or similar names, such as
Maven 'pom.xml' files.  I think a nice enhancement would allow the user
to associate a color with a project, and all files opened to edit
windows from that project would pick up that color in the 1) tab
background or 2) a colored [square behind/box around] the icon or 3) a
color block badge overlaid on the icon. Then as I compare and refactor
between projects, I could easily distinguish between similar or same
named tabs and pull-down menu entries.

I think the tabs are wordy enough that adding the project name as text
would greatly detract from their usability. So I think a color cue would
be the best approach.
