Using the color coding enhancements in Pro Tools 6.7 is a great way to visualize song structure (i.e. Intro, Verse, Chorus, etc.) within your session. To enable these color coding settings, choose Setups > Preferences and click on the Display tab. By setting the Default Region Color Coding to Marker Locations, all regions that start on or after a Memory Location will be colored the same default color (regardless of track) until the following marker. When placing a memory location, be sure to select Marker in the Time Properties section of the Memory Location window.
