The twentieth century

Steiner's work was continued by Theo Gimbel, who established the Hygeia Studios and College of Colour therapy in Britain. Among the principles explored by Gimbel are the claims of Max Lüscher, a former Professor of Psychology at Basle University, who claimed that colour preferences demonstrate states of mind and/or glandular imbalance, and can be used as the basis for physical and psychological diagnosis.
Lüscher's theory!

During the early twentieth century, investigations into the therapeutic uses of colour in Europe were carried out, notably, by Rudolph Steiner who related colour to form, shape and sound. He suggested that some forms amplify the vibrational quality of certain colours, and that certain combinations of colour and shape have either destructive or regenerative effects on living organisms. In the schools inspired by Steiner's work, classrooms are painted and textured to correspond to the 'mood' of children at various stages of their development.
