Hair color based on an oxidation dye precursor reacting with peroxide contains a mixture of: (a) 3-( beta -hydroxyethyl)amino-6-methylphenol (I); and (b) specified substance(s) selected from various aminobenzene and aminophenol compounds and 4-aminopiperidinoaniline and/or their water-soluble salt(s). Hair color based on an oxidation dye precursor reacting with peroxide contains a mixture of: (A) 3-( beta -hydroxyethyl)amino-6-methylphenol (I); and (B) substance(s) selected from 1-( beta -hydroxyethyl)-2,5-diaminobenzene, 2-(2'-hydroxyethyl)-5-aminotoluene, N,N-bis-(hydroxyethyl)-1,4-diaminobenzene, 4-amino-3-methylphenol, 2-amino-5-diethylaminotoluene, 3-(diethylaminomethyl)-4-hydroxyaniline, 2-chloro-, 2-bromo-, 2,6-dichloro- and 2,6-dibromo-4-aminophenol, 2-amino-4-chloro- and -4-methylphenol, 4-aminophenol and/or 4-aminopiperidinoaniline and/or their water-soluble salt(s). If 4-amino-3-methylphenol is used, the presence of 2-amino-6-chloro-4-nitrophenol is excluded.
