Definition

Tristimulus values are defined as the amounts of the 3 reference color stimuli, in a given trichromatic system, required to match the color of the stimulus considered

Background

The International Commission on Illumination (CIE) recommended CIE color specification system as the basis for colorimetry [1]. The ISO and CIE are also provided a series of joint standards [2, 3, 4]. The fundamental of colorimetry is Tristimulus Values [4]. They are used for color communication and reproduction. The three key elements of color perception are: human vision system, light, and object. If missing one of three elements, we will not be able to perceive color. These elements have been defined by CIE as color matching functions of \( \overline{x}\left(\lambda \right) \)
