Hate to break it to you, but all margarine is artificially colored. (Well, if it is yellowish.) Take oil and partially hydrogenate it (i.e. make margarine) and you will get a white-ish/tan-ish product. The Margarine companies then add yellow food coloring to make it look more like butter.
Many years ago, some states (such as Wisconsin) had laws banning the sale of artificially colored margarine. (In Wisc. it was to protect the dairy industry.) So margarine was sold as a white mass with a small packet of yellow food coloring on the side which had to be mixed in to get a visually appealing product. (Wisc. has since rescinded that law.)
