The paper is a specific enrichment of Krajewski's scientific philosophy. According to Krajewski, scientific philosophy embraces scientific fundamentals of philosophy, philosophy of science, scientific metaphysics (ie. ontology), as well as opinions concerning science goals and values relevant for science. However, scientific philosophy does not embrace esthetical issues. The papers postulates an addition of an aesthetic level to scientific philosophy. As a justification and illustration the recommendations of Goethe's and Ostwald's 'Farbenlehren' are analysed.
