And the answer is…

The preliminary answer to my previous question is – works that feature selfsimilarity in Z.
Then I thought, that it can not be implemented without basics of color
theory. So that it is quick, short but selfsimilar in Z. It is just very difficult
to go into Z using only 2bit, or whatever luma based grisaille there is.. because the perceived power of contrast of luma (black vs white) is much weaker than chroma (say yellow vs purple).. Also selfsimilarity in alternative geometries of Z, as it was expressed in works of Leonardo (multi), byzantine art (opposite), spherical (in works of Russian painter Petrov-Vodkin) and others. Luma is important for detail, but not so for Z.

On similarity

Every point is similar to every other point provided that there is enough transformations. Lets imagine a human looking at her reflection in some strange mirror where the mirror image is just a multitude of all possible human faces. Then imagined reflective surface has just to supply the potential of all possible transformations to the the viewer for similarity to happen.
