The first recorded use of Persian red as a color name in English was in 1895.

The Persian red or Persian vermilion is an intense red color, slightly orange, which corresponds to the orange-red glaze of certain monochrome pieces of earthenware made in the parishes of Kerman, Persia, between the end of the XV century and the end of the XVIII.

The Persian red glaze was obtained by means of a clay from the Persian Gulf that contained iron and aluminum and magnesium oxides.

History and uses
Persian red is one of the national and identity colors of Iran, along with Persian green, Persian blue and white. It is the red that appears on the Iranian flag.

On the flag of Iran
The flag of Iran incorporates three of the so-called pan-Arab colors (colors common to the national emblems of Islamic countries): red, white and green. Pan-Arab red originates from the red pavilion used by the Kharijites, the first Islamic republican group to emerge after the assassination of Caliph Uthman Ibn Affan in the 8th century, but the red that Iran uses as a national symbol is specific and different from that of the other pan-Arab flags, and it is “Persian”, as it has been said, because it comes from a color traditionally used in the ceramics of that culture. It has been used in Persian national flags since the 18th century.

In the Red Lion and Sun Society
Before the Islamic Revolution, the Iranian branch of the International Red Cross was called Red Lion and Sun Society (“Society of the Red Lion and Sun”), and had as its symbol the traditional Persian emblem of the lion and sun in Persian red. on white background. This symbol had been accepted by the International Red Cross in 1923, and was used until 1980, when it began to be considered undesirable because the emblem of the lion and the sun came from the deposed Pahlavi dynasty, so it was replaced by the Red Crescent They use the other Islamic nations. However, the red lion and sun symbol is still recognized by the Red Cross, and Iran reserves its ownership and right of use.

In the West
In the West, Persian red was adopted as a color for fashionable clothes, and as a pigment for industrial and artistic paintings. Historically, this pigment has been made with red haematite from the Persian Gulf or by imitation with white lead, potassium dichromate and sulfuric acid.

In human culture
