How does Mars Chocolate determine the color distribution? •“Our color blends were selected by conducting consumer preference tests, which indicate the assortment of colors that pleased the greatest number of people and created the most attractive overall effect.”

•“Each large production batch is blended to those ratios and mixed thoroughly. However, since the individual packages are filled by weight on high-speed equipment, and not by count, it is possible to have an unusual color distribution.”

•Interesting fact: The color distributions differ between bags of milk chocolate, peanut, peanut butter, dark chocolate, almond, and minis.
