 These uses for the word have no relationship to the modern meaning of "chromatic", but the sense survives in the current term "coloratura".The term "chromatic" began to approach its modern usage in the 16th century.For instance Orlando Lasso's "Prophetiae Sibyllarum" opens with a prologue proclaiming, "these chromatic songs, heard in modulation, are those in which the mysteries of the Sibyls are sung, intrepidly," which here takes its modern meaning referring to the frequent change of key and use of chromatic intervals in the work.
