1. A composition for treating keratin materials comprising:
a) at least one amino silicone of formula (I) below:

OG Complex Work Unit Chemistry
in which:
R1, which may be identical or different, represents a hydrogen atom, a phenyl group, a hydroxyl group, a C1-C8 alkyl group, or a C1-C6 alkoxy group;
R2 represents a monovalent radical of formula —CqH2qL in which q is a number ranging from 2 to 8 and L is an amine group, which is optionally quaternized, chosen from the following groups:
—N(R″)2;
—N+(R″)3 A−;
—NR″-Q-N(R″)2; or
—NR″-Q-N+(R″)3 A−,
in which R″, which may be identical or different, represents a hydrogen atom, a phenyl group, a benzyl group, or a saturated monovalent hydrocarbon-based radical; Q denotes a linear or branched group of formula CrH2r, r being an integer ranging from 2 to 6; and A−represents a cosmetically acceptable anion, which is a halide;
R3, which may be identical or different, represents a C1-C8 alkyl group, or a monovalent radical of formula —CqH2qL in which q is a number ranging from 2 to 8 and L is an amine group, which is optionally quaternized, chosen from the following groups:
—N(R″)2;
—N+(R″)3 A−;
—NR″-Q-N(R″)2; or
—NR″-Q-N+(R″)3 A−,
in which R″, which may be identical or different, represents a hydrogen atom, a phenyl group, a benzyl group, or a saturated monovalent hydrocarbon-based radical; Q denotes a linear or branched group of formula CrH2r, r being an integer ranging from 2 to 6; and A− represents a cosmetically acceptable anion, which is a halide; and
m and n are numbers such that the sum (n+m) ranges from 1 to 2000, m denoting a number from 0 to 1999, and n denoting a number from 1 to 2000;
b) at least one non-amino silicone having a weight-average molecular weight of less than or equal to 1500 g/mol; and
c) at least one coloring agent chosen from pigments, direct dyes, or mixtures thereof.
