Galileo filter response compared to Io albedo The colored lines in this graph show the spectral response of the Galileo SSI camera's filters compared to Io's geometric albedo, which is strongly sloped in visible wavelengths but more uniform in infrared wavelengths. The main fact to take away from this graph is that since Galileo lacked a blue filter, so color views tend to be made using the violet filter as the blue channel, where Io is particularly dark, resulting in a strongly yellow overall color to Galileo Io images.
