With his works on paper, the "chromatic color pictures", Mack began to break down light's spectral colors. In every picture the artist renders and contrasts color shades that he differentiates through a certain mix ratio. The range of colors is rich and unusual, at the same time it always creates the impression of a pure and bright color intensity. Owed to its immaterial color and image conception, this work joins the array of Mack's chromatic constellations and an imagery characterized by bright and intense colors.
