There were no red M&Ms while we were at Brookfield Central.
In early 1976, Mars, the candy company that makes M&M’s, eliminated the red version of the candies from their mix. This decision came as a result of public controversy surrounding a synthetic dye called FD&C Red No. 2, also known as amaranth.
Mars reintroduced red M&M’s in 1987, once the panic surrounding anything red had passed.
