I wish that I could somehow upload two photo attachments to a post, but the Biden White House logo doesn not match that used by Trump and a) other recent presidents.
Even the colors don't match? Why is that? I can't find an explanation and I have never seen new presidents use different WH logos nor have I seen any president use any other logo except for the WH logo used by Trump?
There could be symbolism (hollow & blue). But the truth is that every administration makes little changes to the logo to personalized them. Obama did some changes to the one he inherited from Bush and Trump also did some minor changes, as I recall.
