       | But since the pink layer is derived from the wall layer, I am not

       | over the Photoshop-ish approach, of laying the pink over the wall
       | with a "colour burn" blend mode, and using a slightly blurred
       | noisy mask (or distressing the mask layer in some other way).
       | 
       | That could also be set up programmatically in Photoshop (JS) and
       | _probably_ in Krita (Python).
       | 
       | Can you do similar blend mode tricks with scikit-image?
