What religion worships the color purple?

Answer 1

I can't think of any religions which worship colours. In many religions, colours have special symbolic significance.

Purple is generally associated with royalty, and so during advent (the time leading up to Christmas), you will see the altar covered in purple altar frontals to signify the coming of Jesus, who Christians believe to be the "king of kings". However, I don't think The Bible makes many (if any) references to purple, and Christians certainly don't "worship" the colour.
