Comparing bitmaps to assign color to pixels

Is there a way to compare two different black and white images (png). These two tone images that are exactly the same dimensions. Is there a way to have adobe compare the two images (perhaps as layers), and assign a color based on the values comparision? I would also like to distinguish between the pixels that are different, based on how the difference layers (is it white and black, or black and white).

Please post the images.

The Blend Mode »Difference« comes to mind.

Thanks for your post. I will try this out with a red and green pic layer. I should have time later today. I would be happy to give jpeg versions of them, as BMP is not supported. The only reason I mentioned the bmp is the pixel map nature. I am more interested atm in getting the process down at the moment. I can give you examples that would work as a fun place holder. Both of thes images are blown up (102 times), and the grey has been dithered black. Based on 4 possible combination of overlapping pixels (black/black, black/white, white/black, white/white), I would like 1 of 4 colors.

Why the upsampling?

Why the dithering?

Why is the one image colorful and the other not?

Please provide undamaged images.

What is the actual point of the exercise?
