Auburn hair is a variety of red hair, most commonly described as reddish-brown in color or dark ginger. Auburn hair ranges in shades from medium to dark. It can be found with a wide array of skin tones and eye colors, but as is the case with most red hair, it is commonly associated with light skin features. The chemical pigments that cause the coloration of auburn hair are frequently pheomelanin with high levels of eumelanin; however, the auburn hair is due to a mutated melanocortin 1 receptor gene in the people of Northwestern European descent and by a mutated TYRP1 gene in the Austronesians, both genes that reduce the melanin production of the hair cells.
