Does the color of a fruit or vegetable indicate what phytochemicals it contains?
Color is a good, but not exclusive, indicator of phytochemical content. Many, but not all, phytochemicals are pigments that give plants color. Some phytochemicals are colorless. Some phytochemicals are responsible for taste. Sometimes one color may mask another color. Products in a color group will have varying amounts of the same phytochemical.
