Thanks for posting your query. It will be very helpful for me in understanding your condition better if you could answer some of these questions:

1)     Was there any recent trauma to injury to the penis?
2)     Did you indulge in intercourse the night before these symptoms appeared?
3)     Are you able to have normal erections?

Cold and purple penis head which appear all of a sudden is due to compromising blood flow to the tip of the penis. This blood flow obstruction can occur due to any clot, thrombosis, phimosis, obstruction like prostatitis or Mondor’s disease. In Mondor’s disease, there is swelling of a veins under the skin of penis which is caused by a blood clot and is due to superficial thrombophlebitis. It can happen due to circulatory system conditions as well.

It could also be an allergic reaction ,a drug eruption or an infection.

You should get a Urine routine and microscopic examination done. A Doppler ultrasound and a physician examination done from a Urologist would be helpful. You may also need to get a prostatic examination

You can apply warm compresses on the head of the penis and avoid sexual activity and masturbation till that time.
