Colour Group January 2008: Calibrating Color Vision

To reliably signal properties of the world, color vision must be compensated for variations in the spectral sensitivity of the visual system. We have examined the nature of these compensatory processes and how they correct for the perception of white across the visual field, the perception of contrast across different directions in color space, and the perception of hue as saturation varies. Each of these cases suggests that color appearance is calibrated to match the color statistics of the environment, and point to the possible stimulus attributes that color conveys.
