Ten years ago, the designer Hella Jongerius began a research project for the furniture company Vitra to study the properties and possibilities of colours, textures, finishes and materials. This long-term project has resulted in the Vitra Colour & Material Library, which is dedicated to the establishment and further development of an intelligent system of colours, materials and textiles that make it easy to create inspiring environments in offices, homes and public spaces. In the book I Don't Have a Favourite Colour, Hella Jongerius describes her method of research and the application of its results to the Vitra product portfolio
