Have you tried just assigning non-zero pixels to the other image
nonZeroPixels = image1 > 0;
image2(nonZeroPixels) = image1(nonZeroPixels);
If that's not what you want, then explain better.

Put the two images in the same position, with the color image on top, and in the color image set the AlphaData to 1 where the color should be used and set it to 0 where the image underneath should be used.
Note: this will require using the OpenGL renderer.
