M&M colors change with the holidays like Christmas and Easter for instance. I don't go too much by the color or coating. They pretty much all taste the same to me. What is different is the insides. You can get peanut, almond, chocolate, peanut butter and even cherry. Now you can get milk chocolate or dark chocolate. I like the dark chocolate M&Ms and the dark chocolate peanut M&Ms. I like to think the dark chocolate is healthier. That way I can justify eating them.
