‎First appearance of Schrödinger's important three-paper series of a theory of colour measurement for daylight vision. ""His first papers on relativity pointed to a second major field of interest. In addition to these works, and his early papers on relativity, Schrödinger made a detailed study, through both measurement and computation, of the metric of color space and the theory of color vision.""
