Dominant alleles produce colorful pigments, and organisms produce bright rich colors. Recessive alleles often produce little to no pigment at all, so organism are very light in color. When an organism is a , it produces the pigment since it only has making pigment protein. This results in a color that is lighter than a homozygous dominant organism but darker than a homozygous recessive organism. It is an .
