The term 'lacking pigment' can be described by the word 'albino', which is a six-letter word. An albino is an organism that lacks melanin, the pigment responsible for skin, hair, and eye color. Albinism is a genetic condition that affects people of all races and ethnicities. People with albinism often have very pale skin, white or light-colored hair, and light-colored eyes. They are also at risk for vision problems due to their lack of pigment in the eyes.
