Numisia crater, Vesta, in black and white and false color
In this false Red-Green-Blue (RGB) color scheme, red is used for the ratio of the brightness at wavelengths of 750 nanometers to the brightness at 440 nanometers, green is used for the ratio to the brightness of 750 nanometers to 920 nanometers and blue is used for the ratio to the brightness at 440 nanometers to 750 nanometers. Red-blue tones capture the visible continuum and green tones capture the relative strength of the ferrous absorption band at 1 micron. The images have a resolution of about 490 meters per pixel.
