Q: What is the difference between green, yellow and red bell peppers? Dave Baker, Conyers
A: All bell peppers start out with green or yellow-green fruit which then progress through other colors to finally end up with red skin. Different varieties of bell pepper develop different colors between the green and red phases. Some go directly from green skin to red skin. Others go green to yellow to red and still others transform from green to orange to purple to red. Each color tastes differently, with the red pepper having the sweetest flavor.
