TO-31 can take multispectral images.  They are produced by combining data from the Narrow Angle Camera, sensing in the green, red, and near-IR spectra.  Each image has 1020 x 1020 pixels, covering an area of 100 x 100 km at mean ground resolution of 98 meters / pixel.  Red areas indicate healthy vegetation (due to the strong near-IR reflectance of chlorophyll).  Urban areas are generally blue-grey.  The different colors of fields provides an indication of the state of vegetation (bare soil, marsh, young or mature vegetation, etc).
