The CIE, or Commission Internationale de l'Éclairage, is an international organization that focuses on the science of light and its applications. Founded in 1913, its primary goal is to promote knowledge and research in the field of lighting, color, and vision. The CIE develops standards and guidelines that help ensure consistency and quality in lighting design and technology. One of the key contributions of the CIE is the establishment of the CIE color space, which provides a systematic way to describe colors in a standardized manner. This framework is widely used in various industries, including photography, printing, and digital media, to ensure accurate color reproduction and communication.
