When margarine was introduced it was illegal to sell it yellow or butter colored. Margarine came from the store white with a little packet of powdered yellow dye. You would stir in the powdered dye to make it yellow.
Margarine was white and came with a yellow color packet to change it to the color of butter.
Butter is naturally that color. Margarine requires a yellow colorant to mimic the color of butter. before it is colored it is white.
It would be the exact same color as Lard (vegetable shortening): White.
Came with a separate package of a coloring agent which you had to add and mix in yourself. Yellow margarine could not be purchased. Butter was yellow, margarine was white. Lard was white. Yellow was a premium product and laws were passed to insure that you couldn't peddle lard or vegetable oils as the Real Thing.
Well... they still had Black and White movies and, that was the beginning of Color movies.
