In 1783, Richard and Thomas Rowney opened premises in central London where they started selling perfumes and wig powder, which was the beginning of the Rowney Company. As the fashion for wigs soon changed, the Rowney brothers re-focused their talent and concentrated on producing artists' colours. The idea was successful and they soon began supplying famous artists such as Constable and Turner.
