Color Fidelity in Computer Graphics :

The purpose of this paper is to make a state of the art for color delity in computer graphics. Color delity includes three steps. The rst one is the spectral rendering phase which attributes a spectrum to each pixel of a picture. During the second step, a spectral data is transformed into a set of tristimulus values in the XY Z color space. The purpose of the third step, called Color Reproduction Function, is to determine the RGB values displayable on the screen, in such a way that subjective delity is reached. We especially detail the two last steps of the color delity process; we also point out the work still remaining to be done in this eld and we propose some research ways.
