In a lottery, tickets are given nine-digit numbers using only the digits $$1,2,3$$. They are also colored red, blue or green in such a way that two tickets whose numbers differ in all the nine places get different colors.

Suppose the ticket bearing the number $$222222222$$ is green & that bearing the number $$122222222$$ is red, then determine the color of the ticket bearing the number $$123123123$$.
