Jaundice

Means yellowing of the skin from elevated bilirubin, either from the destruction of red blood cells in hemolysis or more commonly from liver disease or obstruction of bile ducts.

Best seen in natural light, it’s often better seen in the sclera (whites) of the eyes, where it is known as scleral icterus
