Psychophysik und Physiologie des Farbensehens

Certain aspects of colour science and colour physiology are presented from the point of view of a linear transfer theory. The following struc­tures are introduced for this purpose: a set of (physical) colour sti­muli, an instrumental colour space, a fundamental colour space, and an opponent colour space. The linear transfer is described by means of mathematical linear mappings between these structures. An important part is played by certain types of colour blind observers, the so-cal­led dichromats. The blue colour mechanism receives a special treatment. The psychophysical results are compared with biophysical and electro­physiological findings. Finally, we present a critique of the colour system CIE 1931.
