Skin color varies from individual to individual. In addition to general skin color, alteration in the skin change can indicate a condition or serious disease.
Skin color is determined by several factors.
a. If more blood enters the skin, the skin appears reddish or pinkish. Therefore, option a is correct.
b. Special pigments of skin melanin determine the skin color. Differences in skin color result from the differences in the amount of melanin production. Hence, option b is also correct.
c. The blood pigment hemoglobin is bright red and the skin appears pink when blood is well-oxygenated. Whereas when the oxygen concentration of blood is low, the skin appears bluish in color. Hence, option c is also correct.
