Color Matching Functions

Color matching functions are mathematical tools used in color science to describe how our eyes perceive color. They define how sensitive the human visual system is to different wavelengths (colors) of light, essentially quantifying how three types of cone cells in our eyes respond to various colors. These functions allow us to predict how a mixture of different lights will appear to us, helping in color reproduction and measurement. In essence, they serve as a bridge between physical light properties and our visual experience of color, enabling devices like screens and printers to produce consistent and accurate colors.
