The series' original logo were stylized letters "GT", the G in blue while the T is in red. This specific version was only used in 1997, for the first game.
Starting with Gran Turismo PSP, the series' logo was given a glossy look.
Starting with Gran Turismo 6 the logo returned to a flat look and is now solely black, or white when on dark backgrounds.
