1. An aqueous-alcoholic dyeing composition A for keratin fibers having a pH in the range of 6 to 12 comprising:
at least one hair dye,
at least one alcohol (b) selected from the group consisting of a C2-C4 monohydric alcohol, a C2-C4 dihydric alcohol, and a C2-C4 trihydric alcohol, and/or their mixtures,
at least one non-ionic surfactant having an HLB value of 11 or less, and
at least one quaternary ammonium surfactant according to the following Formula (I):

OG Complex Work Unit Chemistry
wherein R1 is selected from the group consisting of a C17 to C22 alkyl group and a C17 to C22 alkylene group, R2 is selected from the group consisting of a C1 to C22 alkyl group and a C1 to C22 alkylene group, R3 and R4 are each independently selected from the group consisting of a C1 to C4 alkyl group and a C1 to C4 alkylene group, and X- is selected from the group consisting of a halide anion, a sulfate anion, and a methosulfate anion,
wherein a total concentration of alcohol (b) is 5% by weight or more, based on a total weight of aqueous-alcoholic dyeing composition A,
wherein aqueous-alcoholic dyeing composition A comprises at least one quaternary ammonium surfactant according to the following Formula (II):

OG Complex Work Unit Chemistry
wherein R5 is selected from the group consisting of a C8 to C16 alkyl group and a C8 to C16 alkylene group, R6 is selected from the group consisting of a C1 to C16 alkyl group and a C1 to C16 alkylene group, R7 and R8 are each independently selected from the group consisting of a C1 to C4 alkyl group and a C1 to C4 alkylene group, and Y- is selected from the group consisting of a halogen halide anion, a sulfate anion, and a methosulfate anion, and
wherein a total concentration of the at least one quaternary ammonium surfactant according to Formula (II) is in a range of 0.5% to 10% by weight, based on a total weight of aqueous-alcoholic dyeing composition A.
