  Actually if he used a pure color component for each of the three
magnets, he *already* has the necessary data to re-color the resulting
image. This data is in the image itself: Each color component of each
pixel tells how much the corresponding magnet contributes to that pixel.
Doing a color remapping from this is trivial.
