ABSTRACT:
The present disclosure includes a number of method, medium, and apparatus claims utilized for color sensor performance. One method includes determining performance of a color sensor, which can be performed by measuring a color parameter intensity and reflectance spectral power distribution of a particular type of print medium with a color sensing utility of a print apparatus. The method also can include detecting a magnitude of a difference between the measured color parameter intensity and reflectance spectral power distribution of the particular type of print medium and a predetermined intensity and reflectance spectral power distribution of the color parameter of the particular type of print medium, where the predetermined intensity and reflectance spectral power distribution is stored in memory.
