I can't tell if that's the same color blue in the center but the search engine I used compared the two favorably. I went back to find out why searching on the emblem in the photo of POTUS at the rally brought up links re Barack Obama. Well, there is a picture of the OBama's with what looks like the same seal in an article dated Jan 2019.
Maybe there's a simple reason for the color of the seal - season or commemoration etc.; I just don't know.
Thanks for all the digging on this, r! Great info.
I’m convinced that it’s not just random, that it was intentional and means something.
Maybe it’s a message to the derps and we won’t know.
