CIE Standards refer to a set of guidelines established by the International Commission on Illumination, which is an organization focused on lighting and color. These standards help ensure consistency and accuracy in the measurement and specification of light and color in various applications, including photography, display technology, and architectural lighting. The CIE Standards cover various aspects, such as color spaces, color rendering, and photometry. By providing a common framework, these standards facilitate communication and collaboration among professionals in fields like design, engineering, and science, ensuring that everyone is on the same page regarding light and color measurements.
