Abstract: With the development and the multiplicity of imaging devices, the color quality and portability have become a very challenging problem. Moreover, a color is perceived with regards to its environment. In order to take into account the variation of perceptual vision in function of environment, the CIE (Commission Internationale de l'eclairage) has standardized a tool named color appearance model (CIECAM97*, CIECAM02). These models are able to take into account many phenomena related to human vision of color and can predict the color of a stimulus, function of its observations conditions. However, these models do not deal with the influence of spatial frequencies which can have a big impact on our perception. In this paper, an extended version of the CIECAM02 was presented. This new version integrates a spatial model correcting the color in relation to its spatial frequency and its environment. Moreover, a study on the influence of the background’s chromaticity has been also performed. The obtained results are sound and demonstrate the efficiency of the proposed extension.
