Realize, of course, that what you are asking for is difficult, and, in fact, may not even have any solution.  

For example, consider the case where the colors and tonalities in image 1 are transformed by some procedures into image 2, you are only given the two images, and then asked to find a set of rules that could be used for other images of the same general type.  

Well, a red in the upper LH corner of image 1 may be transformed into a lighter red in image 2, but the exact same red in the lower RH corner of image 1 may be transformed into a darker red in that location.  So, there is no single / unique rule telling one how to transform reds in that image.   Of course, this is a simple example, and one could imagine work-arounds for this.  However, much more complicated transformations are also possible that couldn't be so easily dealt with.

HTH,
