The two computer screens depicting completely different subjects have almost everything in common, in that they are of the same material. However, where they differ -- namely, the color of each pixel -- is where all the information about the painting is contained. So the screens have enough different information (at the quark level) to distinguish what the paintings are about.
So I don't think you are getting at why "about-ness" isn't related to the quarks of the painting. I think a better example is a stick figure. A child's stick figure can be ...
