Strategy To amp up the energy level of a landmark Seattle hotel to bring a playful sense of warmth and collegiality to its original 1928 Art Deco design. Also: to transform its top-floor storeroom into a trio of exclusive suites.     Story Think Gatsby meets Ellington—and Edward Hopper, whose paintings inspired the hotel’s rich palette of golds, blues and persimmon. Original details, including the terrazzo tile floors, were preserved to become an integral part of the hotel’s reincarnation. Public spaces have the aura of glamorous vintage living rooms and libraries. Guest rooms have the easy, elegant luxe of a very posh, very private club. Rising above it all, the Tower takes penthouse life to cool new heights. Each vibrantly colored suite is the essence of one of the high-voltage primary hues used throughout the hotel. Color-infused glass vanities and bars and sleek-lined furnishings give “penthouse chic” a contemporary edge.
