The aim of the research was to determine the role of color in the early development of three species of amphibians (Triturus cristatus, Rana arvalis and Rana temporaria). The experiments were carried out in laboratory conditions, there were run 4-7 replicates. Standard filter systems were used. We monitored pace and stage of eggs' development, the mortality of eggs, and length of the hatched larvae. The color of illumination did not affect the rate of embryonic development of species with a short period of early development (R. arvalis and R. temporaria). Mortality at embryonic stages varied in different species. In all species red light negatively affected the survival of developing eggs. The larvae that started active feeding were larger in all three species with green-blue light than with white and, the more red, light.
