As my research and the article stated, only two colours are used in Sophocles' Aiax: black – 5 times, and white – 3 times (3 times in the choral and 5 times in the dialogic parts of the tragedy), expressed by 8 colour terms (4 simple and 4 complex).

The black, as so-called dominant colour – an Aeschylian artistic and chromatic device – is used by Sophocles in Aiax to underline the main personages, ideas and motifs of the play (namely: the blood that will be shed; the fatal sword gifted by Hector to Aiax and used by him to kill the herd in the beginning and to commit suicide in the end of the play; Odysseus, an enemy who turned into a friend, determining the course of the tragic conflict). Not only the principle of colour used, but also the word combinations – in which the black colour is used – are influenced by Aeschylus. At the same time, an indirect connection can be seen between the "black sword" of Aiax and the "black arrow" of the Erynies in the "Choephoroi" by Aeschylus (see: "Aiax", 229-230, "Choephoroi", 283-287). Therefore it can be assumed that the artistic and namely chromatic vision of Sophocles in Aiax can be compared with the Aeschylian one, proving the famous reference of Plutarchus: "Sophocles used to say that he had fought his way through the pomp of Aeschylus" (De prof. in virt., 79 b).
