The first M&M’s came in six colours: brown, yellow, orange, red, green and violet. Then, in 1949, violet was switched to tan. Later, the company asked customers to vote for which colour they wanted in the pack and the winner was blue. Nowadays, you’ll find brown, yellow, orange, red, green and blue. But, as fans of the candy will know, they all taste the same: the shell doesn’t signify a flavour.
