Because of the economic importance of fruit color, environmental factors influencing its development have been carefully researched. The primary determinant for fruit color is genetics, and by selection of crosses for desired color effect, a variety of colors have been maintained and offered to consumers.
In isolated cases, a fruit cultivar desired by consumers may not accumulate enough pigments to meet some established standard. The standard may be market acceptability or may be imposed by an overseeing body such as the U.S. Department of Agriculture Fruit Inspection Service. Commodity quality standards might relate to percent color coverage of the surface or to color intensity.
