Changed wedding colors after Save the Dates were purchased.

Tell me that I am just tripping. I purchased STDs to send out to out of town guest only (30). The STDs are greenish and I think I want to change my wedding color to a deep purple.

I don't want to lose $$ and I am sending them out 8 months before the wedding. I don't think guest will remember and they will be in the trash by month 6. lol

Do you agree?
