As in this monochrome view of Mercury, the bright rays of Hokusai crater can be seen crossing the surface from north to south. This color image, with the central wavelengths of 1000 nm, 750 nm, and 430 nm displayed in red, green, and blue, respectively, also highlights some of the subtle color variations observed on Mercury. Spectral variations can be due to differences in particle size, duration of time exposed on surface, or composition. The MESSENGER team is working hard to unravel the complicated story contained in these beautiful color images.
