Saul Bass was an American graphic designer and film title sequence designer who was notable for his use of simple geometric shapes and animation to capture the mood and essence of films. He is best known for his imaginative title sequences and logo designs that used minimalist graphics to deliver powerful messages about the themes and tones of movies. His titles for films like West Side Story employed shifting colors and faint lines to represent the setting and build dramatic tension through the music, foreshadowing the film's romantic and dramatic elements.
