Spatial effect in color vision

Traditionally, color vision studies focus on the change of the power spectrum distribution (the energy at each wavelength of the light) of the visual stimuli rather than the spatial modulation. However, the spatial context does affect color perception. Currently, our research on this issue has been focused on psychophysical measurements. So far, the projects on issue focused on the same issues and paradigms we used for spatial context effects in general. The only difference was using isolumiant modulated stimuli rather than luminance modulated ones.
