Comparing Greyscale Images

At right are three greyscale images obtained using red, green, and blue filters. Notice in each image where it is dark and where it is bright. A color (red, green, or blue) is then assigned to each of the filtered greyscale images. This is known as colorizing the image. Finally, the three colorized images are combined to create the full color image shown on the right.
