👉 A photochromolithograph is a type of photographic process that uses a sensitive material to change its color response under different conditions, such as sunlight or darkness. In this process, the light-sensitive material is exposed to different wavelengths of light and then changes its color response based on the presence of specific chemical compounds in the material. The key components of photochromolithography include a sensitive material (such as a metal or a semiconductor) that can absorb or emit certain colors under different conditions. The material
