Acanthosis Nigricans is what you are suffering from, a skin condition that causes your neck to darken compared to the rest of your body. This may occur if you are obese or have diabetes.

A balanced diet, regular exercise, and maintaining the cleanliness of your skin can gradually improve this problem.
