| 1. A keratin dyeing composition comprising:
(A) a medium suitable for dyeing; and
(B) one or more tricyclic fused 6-5-6 heteroaromatic keratin dyeing compounds having one heteroatom according to the following
formula:
 wherein Y is independently selected from the group consisting of NA1 and O;
wherein R1, R2, R3, R4, R5, R6, R7, and R8 are the same or different and are selected from the group consisting of:
(a) C-linked monovalent substituents selected from the group consisting of:
(i) substituted or unsubstituted, straight or branched, alkyl, mono- or poly-unsaturated alkyl, heteroalkyl, aliphatic, heteroaliphatic,
or heteroolefinic systems,
(ii) substituted or unsubstituted, mono- or poly-cyclic aliphatic, aryl, or heterocyclic systems, and
(iii) substituted or unsubstituted, mono-, poly-, or per-fluoro alkyl systems; wherein said systems of (i), (ii) and (iii)
comprise from about 1 to about 10 carbon atoms and from about 0 to about 5 heteroatoms selected from the group consisting
of O, S, N, P, and Si;
(b) S-linked monovalent substituents selected from the group consisting of SA1, SO2A1, SO3A1, SSA1, SOA1, SO2NA1A2, SNA1A2, and SONA1A2;
(c) O-linked monovalent substituents selected from the group consisting of OA1, and ONA1A2;
(d) N-linked monovalent substituents selected from the group consisting of NA1A2, (NA1A2A3)+, NA1OA2, NA1SA2, NO2, N═NA1, N═NOA1, NA1CN, and NA1NA2A3;
(e) monovalent substituents selected from the group consisting of COOA1, CONA12, CONA1COA2, C(═NA1)NA1A2, CN, and X;
(f) fluoroalkyl monovalent substituents selected from the group consisting of mono-, poly-, and per-fluoro alkyl systems comprising
from about 1 to about 12 carbon atoms and from about 0 to about 4 heteroatoms; and
(g) hydrogen;
wherein A1, A2, and A3 are monovalent and are independently selected from the group consisting of: H; substituted or unsubstituted, straight or branched,
alkyl, mono- or poly-unsaturated alkyl, heteroalkyl, aliphatic, heteroaliphatic, or heteroolefinic systems; substituted or
unsubstituted, mono- or poly-cyclic aliphatic, aryl, or heterocyclic systems; and substituted or unsubstituted, mono-, poly-,
per-fluoro alkyl systems or A1 and A2 together with nitrogen atom to which they are bound form a ring; wherein said systems comprise from about 1 to about 10 carbon
atoms and from about 0 to about 5 heteroatoms selected from the group consisting of O, S, N, P, and Si, with the proviso that
when R1, R3, R6, and R8 are the same, R1, R3, R6, and R8 are not NH2; and
wherein X is a halogen selected from the group consisting of F, Cl, Br, and I.
