As your relative is a diabetic it's possible that he might be suffering from peripheral arterial disease where the blood vessels to the leg get blocked and hence tha change in colour. He will need a doppler to confirm and an angiogram if necessary.  Please consult a general physician to accurately diagnose. If it is PAD then further management will be by a vascular surgeon / interventional radiologist.
