Riviera, Maritime, Gulf, Voodoo, San Marino, Oslo – however you like your Porsche, a shade of blue can elevate almost any era of the rear-engined sports car to another level. While trending shades of Emerald Green and Rubystone Red have always been colours the bravest of owners flock to, the variation in sky-blue shades allow owners to bring their sense of style directly to the models like the 992-generation 911, and all the way back to the 928.
