From its formation in the late 1960s, Swiss textiles company Mira-X worked closely with Danish architect Verner Panton in a partnership that continued through two decades and produced dozens of predominantly geometric designs for fabrics and carpets. Perhaps the most iconic and influential of these was the Mira-X Spectrum set of 1971, based on different combinations of eight colours and five motifs (square, circle, stripes, curve and chequers) and produced in three different scales in ratios of 1:3:9.
