Before your (our) time, but only barely. Margarine was originally crisco-colored (or close to it,) but the American housewife wouldn't use it because it didn't look like butter. Until the advent of commercial food coloring additives, companies would but a little packet of yellow dye that could be mixed into the margarine. Voila! Instant "fool the family" butter!
I've read that the reason for the dye packet, rather than just coloring it at the factory, was because of laws against selling margarine that was colored the same as butter.
