About byzantium

The color Byzantium is a particular dark tone of purple. It originates in modern times, and, despite its name, it should not be confused with Tyrian purple, the color historically used by Roman and Byzantine emperors. The latter, often also referred to as "Tyrian red", is more reddish in hue, and is in fact often depicted as closer to crimson than purple. The first recorded use of byzantium as a color name in English was in 1926.
