Global Image of Io (True Color) - NASA Science
WEBAug 27, 1999 · NASA's Galileo spacecraft acquired its highest resolution images of Jupiter's moon Io on 3 July 1999 during its closest pass to Io since orbit insertion in late 1995. This color mosaic uses the near-infrared, green and violet filters (slightly more than the visible range) of the spacecraft's camera and approximates what the human eye would see.
Io (moon) - Wikipedia
WEBIts volcanic plumes and lava flows produce large surface changes and paint the surface in various subtle shades of yellow, red, white, black, and green, largely due to allotropesand compounds of sulfur. Numerous extensive lava flows, several more than 500 km (300 mi) in length, also mark the surface.
