During the season 4 depiction of Charles and Diana's 1983 PR-driven Australian tour, what color is the stunning dress she wears to the Wentworth Hotel Ball?

Diana became a close friend and regular customer of designer Bruce Oldfield during her early years as a royal. One of the first mixed-race fashion designers in England, Oldfield found a dedicated champion in the young princess. Diana even helped Oldfield raise thousands for the institution where he, a half-Jamaican orphan, grew up.
