1. A method for color transformation, the method comprising: electronically transforming a monochromatic infrared source image of a source scene into a natural daylight color image of said source scene as a function of reference information, wherein the only information derived from said source scene and utilized in said transforming being said monochromatic infrared source image, wherein said electronically transforming includes: accessing a pair of reference images of a reference scene, wherein said pair of reference images includes a monochromatic infrared reference image of said reference scene and a natural daylight color reference image of said reference scene, wherein pixels from said monochromatic infrared reference image are co-located with pixels from said natural daylight color reference image; matching luminance values from pixels in said monochromatic infrared source image to luminance values associated with pixels in said monochromatic infrared reference image; and assigning color values to said pixels in said monochromatic infrared source image from color values associated with said pixels in said natural daylight color reference image based on a mapping from said pixels in said natural daylight, color reference image to pixels in said monochromatic infrared reference image and said matching between said pixels in said monochromatic infrared reference image to said pixels in said monochromatic infrared source image to generate said natural daylight color image of said source scene.
