Galileo acquired a few global color views of the Galilean satellites. The examples shown here of Europa, Callisto, and Ganymede are "true color" views that have not been colorized or have had their color data pulled from orbits different than those from the images used to create the mosaics (which is the case for many global mosaics). Due to inconsistent filter selection when the images were taken, there are some variations between images.
