Spotting Accidentally Layered Regions in Logic

Part of what makes DAW programs so great is the simple ability to cut and paste parts of an arrangement into other parts of a song. It really helps speed up the workflow of building a song's structure and lets you experiment with it quickly and freely without a lot of effort.

If you're like me, however, you've probably accidentally pasted a region (or whole section of regions) over an existing region without realizing it once or twice. There are usually audio clues to point this out to you (either a sort of comb filtered/flanged sound to the layered section, or a dramatic increase in volume in the offending spot...), but Logic also gives you a subtle visual cue, which can help you spot these goofs quickly.

As in the above picture, the section that has other regions 'hidden' beneath it shows up in a slightly lighter shade of gray than normal. It's a simple thing, but little visual clues like this can be very helpful when you initially can't figure out why the volume of your bassline suddenly leaps during one section when you haven't written any volume automation.
