| Color: |
This image was made using data from a single filter in the near-infrared part of the spectrum so it is in fact monochrome or black and white. The color results from mapping each brightness step in the grayscale image to a separate color, known as a color-mapped or color-indexed image. In this case the color scale is a ramp from black through red and orange to white. |
