| 1. A composition for dyeing keratinous fibers comprising
(i) at least one cationic direct dye chosen from compounds having the following formulae (I), or (III):
a) compounds of following formula (I):
 D is a nitrogen atom or a —CH group,
R1 and R2, which are identical or different, are chosen from a hydrogen atom; a (C1-C4) alkyl radical which may be unsubstituted or substituted with a —CN radical, an —OH radical or an —NH2 radical or form with each other or with a carbon atom of the benzene ring an optionally oxygen-containing or nitrogen-containing
heterocycle which may be unsubtituted or substituted with at least one radical chosen from (C1-C4) alkyl radicals; and a 4′-aminophenyl radical,
R3 and R′3, which are identical or different, are chosen from a hydrogen atom; a halogen atom chosen from chlorine, bromine, iodine,
and fluorine; a cyano group; a (C1-C4) alkyl radical; a (C1-C4) alkoxy radical; and a (C1-C4) acetyloxy radical,
X− is an anion,
A is chosen from the following structures A1, A7, and A19:
 wherein:
R4 is a (C1-C4) alkyl radical which may be unsubstituted or substituted with a hydroxyl radical, and
R5 is a (C1-C4) alkoxy radical; and
b) compounds of following formulae (III):
 R13 is chosen from a hydrogen atom, a (C1-C4) alkoxy radical, a halogen atom chosen from bromine, chlorine, iodine and fluorine atoms, and an amino radical,
R14 is chosen from a hydrogen atom, and a (C1-C4) alkyl radical, or forms, with a carbon atom of the benzene ring, a heterocycle which optionally contains an oxygen heteroatom
and which is unsubstituted or substituted with at least one radical chosen from (C1-C4) alkyl radicals,
R15 is a hydrogen atom or a halogen atom chosen from bromine, chlorine, iodine and fluorine,
D1 and D2, which are identical or different, are a nitrogen atom or a —CH group,
m is 0 or 1, with the proviso that when R13 is an unsubstituted amino group, then D1 and D2 simultaneously are a —CH group and m is 0,
X− is an anion,
E is a group chosen from the following structures E1, E2, and E7:
 wherein said composition further comprises (ii) at least one silicone chosen from:
(ii)1—aminated silicones
(ii)2—polyoxyalkylenated silicones; and
(ii)3—silicone gums and resins.
