Metal panels do not "insulate" per se. The new cool paints reflect heat back into the atmosphere, which helps reduce energy consumption in predominately cooling load climates. In predominately heat load climates, it would actually be better to not use cool paint.
In climates that are about half and half, such as what you describe, I would use the cool colors in conjunction with a minimum 3/4 air gap and a radiant barrier insulation. This combination should give you the best energy efficiency for both summer and winter.
