a warm gray color they called "Platinum" for the IIGS and all subsequent computers until the introduction of the iMac in 1998 (although a darker shade of gray was adopted for the PowerBook line and various peripherals). The original Macintosh was designed by Jerry Manock and Terry Oyama with ample guidance from Steve Jobs. In doing so, they unwittingly created an enduring iconic design. Though variously redressed in "Snow White" details (such as the Macintosh SE), all the way to the translucent iMac, there is a legacy imparted by the original Macintosh design. Having worked 90-hour weeks, Manock and the rest of the Mac team were exhausted, and he failed to register the Macintoshes in time for the design award consideration. Esslinger would not make the same mistake with the SE and ultimately received the recognition denied Manock, which often led to Esslinger being credited with the original design of the Macintosh, a perception Esslinger and Frog Design always corrected. However, by the end of 1985, Steve Jobs resigned from Apple and Hartmut Esslinger and his Frog Design team followed, later working with Jobs at NeXT. Reformation By the early 1990s, Apple discovered that the Snow White language that had served them so well through the 80s was being copied by its generic IBM PC competitors, causing Apple to lose some of its unique identity. With the move away from Frog Design, Apple chose to bring all industrial design in-house by creating the Apple Industrial Design Group, headed by Robert Brunner except for portable computer devices design projects led by Kazuo Kawasaki. Though many of the new designs reflected the legacy of Esslinger's Snow White language, the new design group began to rapidly move in its own direction, which can be clearly seen in landmark products of the Espresso language such as the Macintosh Color Classic. The list of innovative designs which clearly defined Apple products in the marketplace continued through the 90s. Return of Steve Jobs The return of Steve Jobs in 1997 ushered in a new era for Apple design, and the appointment of designer Jonathan Ive, drawing heavily on the design philosophy of Dieter Rams for Braun, and infusing them with vibrant color and translucent details. The launch of the iMac in 1998 also drew on some of the iconic elements of the original Macintosh, such as the all-in-one format and top-mounted handle. The successive design language
