Where: R 1-R 3, R 6, R 8, R 7, R 9-R 12 do not comprise a peroxide bond, diazo or nitroso radicals; R 1-R 3, R 6, R 8 do not contain nitro radicals; R 3 is not linked to the pyridine ring by S, N, or O; R 1, R 2, R 11, R 12 and D are not directly linked to N by S, N, or O; R 7 and R 9 can be independent from each other; radicals R' can be different from each other, when n is strictly greater than 1; and (I) does not comprises more than one cationic radical D1-Z. Independent claims are also included for: (1) direct dye (I); and (2) coloring the keratinous fibers comprising applying (A) to obtain desired coloration.
