CIE 1931 color space

The CIE 1931 color space is a system developed to describe and quantify colors based on human vision. It uses mathematical models to map colors according to how the human eye perceives them, primarily through two parameters called x and y, which represent the proportions of red, green, and blue light. This system creates a standardized chart known as the chromaticity diagram, where each point corresponds to a specific color. It helps in designing and comparing colors accurately across various fields like lighting, displays, and photography by providing a common language for color representation.
