Design trends in the 1970s were marked by a backlash against the bright colours and futurism of the 1950s and 1960s and a rise in popularity of dark, earthy tones with extensive use of brown, green, purple, and orange. These darker colours reflected the back-to-nature mindset of the decade. Wood decor and paneling was integral to 1970s interior design as well, replacing the obsession of the 1950s and 1960s with chrome and aluminum. In architecture, buildings were created with more open space and groundbraking geometry. Many of the above mentioned style elements are at this moment being reinvented as contemporary design items, as can be seen in the images.
