 From 1838 to 1840 Fechner undertook experiments on the psychology of sense perception. In doing so he became part of a Leipzig tradition: in the 1830s Alfred Volkmann (1801–1877), and Ernst Heinrich Weber (1795–1878) and Eduard Friedrich Weber (1806–1871) had conducted experiments on the psychology and physiology of sense perception. Fechner continued in that tradition by conducting experiments on color perception. He wanted to investigate the connection between the objective phenomenon of light and its subjective perception. He discovered that the appearance of many color phenomena is due more to retinal fatigue rather than any property of light itself. Fechner’s results proved fruitful and were later taken up by  Helmholtz.[6]
