Kevin"one can't intentionally remove just one while leaving the others behind"
Sure it can...I've done it many times but it does depend on the colors. Look closely at the soccer player, it has the same pre-war baseball card printdots that are blended and overlapping, yet the yellow on the bottom has been removed leaving the dark green/olive and black behind...just like the e93 Brown.
btw...some proofs and progressive proofs can be made as well.
As mentioned "It may just be a futile point" even when examples are shown.
Just imagine what is not being shown
