For the question regarding the color of airports on IFR charts, the answer is a bit misleading. It merely says “blue are military” regarding airports depicted in blue. A cursory examination of any IFR low chart will show that there are plenty of non-military airports which are depicted in blue. The blue color indicates that their are high altitude military approaches available at that airport, but not that the airport is itself a military airport.
