Agents and methods for the oxidative coloring of hair on the basis of a coupler substance / developer substance combination, whereby as a coupler substance (A) 5-amino-2-methylphenol and as developer substances (B) 4-amino-3-methylphenol and (C) 1,4-diamino-benzene and / or 2,5-diamino-toluene, also in the form of the physiologically acceptable salts, can be used. Das neue Mittel ermöglicht die Herstellung neutraler roter Farbtöne, die frei von Gelb- und nahezu frei von Blauanteilen sind und neben der hohen Farbintensität und Leuchtkraft eine hervorragende Farbegalität bei sehr gutem Aufziehvermögen aufweisen. The new agent enables the production of neutral red shades that are free of yellow and almost free of blue components and, in addition to the high color intensity and luminosity, have excellent color levelness with very good drawability.
