What hair colour makes ginger?

Ginger hair, often referred to as red hair, is a result of a specific variant of the MC1R gene that affects melanin production. This gene variant leads to an increased production of pheomelanin (which provides red and yellow hues) and a decreased production of eumelanin (which gives darker shades). The combination of these factors results in the characteristic fiery orange-red color associated with ginger hair.
