I would suggest, from where you are above you could do something like:

from PIL import Image
from PIL import ImageChops

a = Image.open("pict1.jpg")
b = Image.open("pict2.jpg")
diff = ImageChops.difference (a, b)
RED = ('red')
RL = Image.new('RGB', diff.size, RED) # Make a red layer the same size
RedDiff = ImageChops.multiply(RL, diff)
Result = ImageChops.blend(RedDiff, b, 0.7)
Result.show()

enter image description here

try to read your images to separate arrays and compare arrays together

then manipulate the diff parts by change the color you want
