Abstract
A profile generation module which generates colorimetric color profiles based on spectral data and user input on viewing conditions, light source, and medium. In situations where the available color profiles are colorimetric, the colorimetric color profiles are passed to the color management system. In situations where spectral color profiles are available, the profile generation module accesses the spectral profile and the user input. If the user input specifies a medium, the profile generation module also accesses the media module to predict spectral reflectance data for the specified medium. The profile generation module generates the calorimetric color appearance profile based on the user input, and generates the calorimetric color device profile based on the user input and the spectral data. In this way, calorimetric color profiles are generated as needed, and spectral data can be used with calorimetrically based color management systems.
