Marks: The purple marks are usually due to laxity of the skin and atrophy of the orbital fat causing a concavity. This concavity causes a shadow affect giving the purple appearance. Also the thinning of the skin can make the blood vessels and vasculature more visible causing the purple affect.

Cold compress: Purple or blue marks under eyes may be due to blood vessels under eyes. Cold ice packs might help marks decrease by contracting the vessels.

Purple under-eye : First start with a complete skin and facial exam to see exactly what is going on. Cool compresses and some eye creams can be beneficial as a starting point. Retin-a can be of benefit in the right candidate. A dermal filler, laser procedure or surgery may be needed depending on findings and the amount of correction you are looking to achieve.
