It is an Air Force craft, after all

Donald Trump doesn't like the "baby blue" that's part of the exterior color scheme of the presidential airplane.

Hmm. I always took it to be "sky blue," as in the center of the United States Air Force logo.

That seems appropriate for an aircraft designated as Air Force One.

Historian Michael Beschloss shares this regarding the font President Kennedy chose for the fuselage of the plane.

JFK chose font for “UNITED STATES OF AMERICA” on fuselage of Air Force One because it resembled font of early printed version of Declaration of Independence: pic.twitter.com/LOQ9KgAnOd
