Chromogenic refers to a process or material that produces color through chemical reactions. This term is often used in photography, where chromogenic prints are created using color negative film. In this process, the film captures images in color, and the development involves chemical baths that reveal the colors. In addition to photography, chromogenic materials can be found in various applications, including textiles and paints. These materials change color in response to environmental factors, such as temperature or light. Chromogenic technology is also explored in fields like sensors and displays, where color changes can indicate specific conditions or information.
