They don't have the gene that leads to the creation of the protein for coloring.
The pigment containing iron is called hemoglobin. Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body.
Urine and feces are the wastes that are expelled from the human body.

The blood pigment of an insect is called hemolymph. Hemolymph is a fluid that circulates through the insect's body and helps transport nutrients, hormones, and waste products. It is functionally similar to blood in vertebrates.
The pigment melanin gives color to human skin, hair, and eyes. Melanin is produced by specialized cells called melanocytes and helps protect the skin from harmful UV rays.
The dark pigment of the body is called melanin. Melanin is responsible for determining the color of our skin, hair, and eyes. It helps protect the skin from the damaging effects of the sun's UV radiation.
Pigment cells (melanocytes) are found in the basal layer of the epidermis.
Grey hair occurs when the pigment-producing cells in hair follicles gradually decrease in number and activity as we age. This leads to a reduction in the production of melanin, the pigment that gives hair its color. As a result, new hair grows in without pigment, appearing grey or white.
