Detailed explanation-1: -Human skin colour is determined by three major pigments. Haemoglobin contributes to red colouration, melanin which darkens and yellows the skin colour and carotenoids which contribute predominantly to skin yellowness (Alaluf, Heinrich, Stahl, Tronnier, & Wiseman, 2002.
Detailed explanation-2: -Hemoglobin is the iron-containing protein pigment of our blood cells. A lack of oxygen saturation imparts a paler, grayer, or bluer color to the skin. Skin may also become paler as a result of anemia (a reduced number of hemoglobin and/or red blood cells), low blood pressure, or poor circulation of blood.
Detailed explanation-3: -The surprising fact is eating too many carrots, or other foods high in beta-carotene, can cause a yellowish discoloration of the skin, according to the Dermatology Clinic at UAMS. This discoloration, a condition called carotenemia, is most noticeable on the palms and soles.
