asked:
Just an Age of Ultron production question. Why are the wordballoons in the past colored grey? Was it just another way to delineate a different era along with the different font & hand drawn wordballoon?

Yes. We made the choice in issue #6 to give the word balloons of any character from that era a slight tone, one hat simulates the coarser paper stock that was used in those days.
