Is it possible to make changes over several clips at the same time when color correcting?
2 ideas for Premiere CC 2015:


Apply effects to the source clip instead of just the part on the timeline. If you're targeting clips from more than one camera original, you could nest the camera originals into a sequence, use that sequence as your source, and apply color effects to the source clip. That should populate your changes to one clip to all the rest from that source sequence.
Use an adjustment layer to apply the same effect to a series of adjacent clips.
