Hi!
Yes, at his age it can be a circulation problem or a heart disease or sever anemia causing low oxygen supply to tissues and hence this discoloration. It can also be due to extreme cold. Hypothyroidism and low vitamin B12 is another possibility. It is very important to take your grandfather to a doctor as soon as possible. A comprehensive investigation is required keeping all the points in mind. Take care!
