This red colour comes from madder (Rubia tinctorum) root with alkali. Dyestuffs can produce different shades depending on the pH of dyebath. Historically different substances were used as alkali, sometimes really smelly (as an urine), we prefered to replace it with kitchen soda though.
Basic dyeing substance in this combination, madder, is one of the most ancient dyes (it was used by the early Egyptians, and the Greek and Romans). In Medieval times madder root was traded in markets all over Europe – especially in France and England. The red colour from madder was loved by Vikings. Among them, red clothes were worn even by kings, and often given as a precious gift.
