Each designer has developed his own colour palette within the Vitra Colour & Material Library based on his aesthetics, the design approach and the furniture shape. The library guarantees that almost all colours, surfaces and textiles are easy to combine or offers matching colour partners – even across the different Designer libraries. In addition, the so called signature colours make the individual palettes unique for each designer. Signature colours are shades that can only be used by one designer. They are sometimes even limited to one product only. Usually, designers themselves will suggest a signature colour because they like that specific shade or have a particular role in mind for this colour. When re-introducing classic designs, a decision will be made in close cooperation with Hella Jongerius and the respective designer’s family or heirs.
