Jaundice is caused by increased deposit of bilirubin in tissues caused by liver disease or destruction of red blood cells; it is not characteristic of anemia. Cyanosis is caused by an increased amount of deoxygenated hemoglobin due to heart or lung disease or a cold environment; it is not characteristic of anemia. Erythema is caused by increased visibility of oxyhemoglobin due to dilation or increased blood flow because of fever, direct trauma, blushing, or alcohol intake; it is not characteristic of anemia.
