Zusammenfassung:	Articles injection molded from colored poly(arylene ether) compositions can exhibit an esthetic defect known as black rings. The black rings can be reduced or eliminated when the poly(arylene ether) composition includes about 50 to about 70 weight percent of a poly(arylene ether), about 12 to about 30 weight percent of a rubber-modified polystyrene, about 5 to about 25 weight percent of an organophosphate ester flame retardant, and a first colorant and a second colorant, wherein the total amount of all colorants is about 0.3 to about 1 weight percent.
