The term famille rose refers to the color palettes used in Chinese porcelain. Famille rose was introduced late in the reign of the Kangxi Emperor (1661–1722), possibly around 1720. It used mainly pink or purple and remained popular throughout the 18th and the 19th centuries, also being widely adopted by European factories. Famille rose enamel ware allows a greater range of colour and tone than was previously possible, enabling the depiction of more complex images, including flowers, figures and insects.
