Such views can be used to highlight subtle color differences on Ceres&#8217; surface. Lower resolution color data have been overlaid onto a higher resolution view (see PIA20350) of the crater. The view was produced by combining the highest resolution images of Occator obtained in February 2016 (at image scales of 35 meters, or 115 feet, per pixel) with color images obtained in September 2015 (at image scales of 135 meters, or about 440 feet, per pixel). The three images used to produce the color were taken using spectral filters centered at 438, 550 and 965 nanometers (the latter being slightly beyond the range of human vision, in the near-infrared).
