The Rainbow Room was originally designed by architect Wallace K. Harrison, of Rockefeller Center's Associated Architects, as well as interior designer Elena Bachman Schmidt. Harrison was one of the Associated Architects' principals, but he was not the complex's main architect; that distinction belonged to Raymond Hood. However, Hood's health was deteriorating by 1933, and as the months passed, Harrison had an incrementally increased involvement in Rockefeller Center's design. John R. Todd, the main consulting architect, attributed the terrace layout of the Rainbow Room to one of Harrison's designs. Schmidt, a one-time apprentice of Elsie de Wolfe, contributed to the design of the interior decor, such as the furniture, curtains, and elevator doors. Vincente Minnelli who would later become a film director, was assigned to help Schmidt select the colors of the walls. The walls were ultimately decorated in a plum purple pattern, as were the blinds and linens in the Rainbow Room. The restaurant's original architectural style was characterized as something that "bows to the ladies steps back in a kind of restrained Oriental way" by the magazine "Arts & Decoration", and as "modern, like most post-Repeal ventures" by "Architectural Forum". The 1987 renovation brought the Rainbow Room into an "American Modern" or simplified classical style.
