Right-click anywhere inside the track you wish to change the background color of. From the resulting pop-up menu click on "Current Track Event Colors". Click on "Choose", where you can then select from a whole slew of track colors. "OK" your way out after making your selection; the track you are in (assuming there is already something recorded in it) will turn to the color you have selected. Nice feature; I wonder how many people are aware of this new addition?
