Scientific paper

Fifty years have elapsed since W. Becker (1938) proposed to use threecolour photometry for the study of stars which are too faint for spectral c1assification. He stressed that the choice of the passbands had to be guided by the properties of stellar radiation rather than by the properties of existing instruments. The three passbands were chosen such as to reflect the two basic characteristics of the visible spectral energy distribution of astar: a longwave colour index (G-R) as a measure of temperature and a short wave colour index (U-G) defined by two weil separated passbands measuring the UV-depression caused by line blocking and the Balmer depression.
