Voyager camera filter response compared to Io albedo
The colored lines in this graph show the spectral response of the Voyager ISS camera's filters compared to Io's strongly sloped geometric albedo. The main fact to take away from this graph is that the Voyager camera is most sensitive at wavelengths where Io appears darker, and that the choice of violet or blue filters to use for the blue channel in a color composite will make a big difference in Io's apparent color.
