Techopedia Explains CIE Color Model

The CIE color space was created back in 1931 in order to map out all the colors that can be perceived by the human eye. It was made independent of any technology that may present colors, which is why it is considered to be the most accurate color model. The CIE Color model is a three-dimensional model that takes account of the chromatic response of the eye; a response which changes as the cones across the retina differ in their reaction to light and color in different areas of the retina.
