Postmodern Design is a decorative movement that began in the late 1970s through the 1920s. It was born out of a reaction against modernism and its principles of functionality and minimalism. Postmodern designers sought to challenge these principles by creating more expressive, eclectic and often humorous pieces. Postmodern style is characterized by the use of bright, contrasting colors, intricate patterns and unexpected materials. Designers often mixed styles and patterns to create unique and original works whose forms were often deconstructed or distorted. The postmodern movement was also marked by great freedom of expression.
