The margarine people must have learned this from the cheese makers. Margarine without coloring looks like white like a slab of lard.

Back in the late 1940s or very early 1950s, margarine came with a coloring packet of some sort. I do not remember it, but my older sisters remember getting the job of mixing the coloring in.
When I was a child in CA, colored margarine was illegal. Margarine came in a brick, had to be softened, and then you had to stir the color in. It was a lot of work, but the Dairy Lobby kept a tight rein on the rules.
After WWII, the margarine folks started marketing margarine in plastic bags with a dye bubble in the middle. Yoou could squeeze the bubble to break it and then knead the bag until the color spread throughout the white margarine evenly.
Coloring the margarine was my chore when I was 6-10.
