Sažetak We discuss within one common context topics of color symmetry, using semigroups for generalization
of symmetry, fractals, and some naturally occurring interrelations thereof. This free essay is emotionally
inspired by the impressive scientific work of Prof. Douglas Jay Klein and his numerous collaborators,
who contributed into diverse fields of chemistry, physics, and mathematics. (doi: 10.5562/cca2303)
