A close look at the provided texts reveals that none of the examples use “Byzantium” in the sense of a color at all—instead, they almost uniformly refer to the ancient city or empire. While “Byzantium” is known in modern contexts as a deep, rich purple hue full of connotations of opulence and antiquity, none of the texts here employ it to describe a visual quality or a tint; for instance, in [1] the term is used metaphorically to indicate an emerging presence rather than to evoke a particular color, and all the other examples similarly invoke Byzantium’s historical or political significance rather than its chromatic identity.
