In order to help patients reduce their chronic pains, scientists have come up with an idea where they are going to assign color Blue to pain.

For this they will be re-routing the signals that cause the feeling of pain and will allow the sufferer to see it with color Blue. They can also assign smell or sound to it but that would require some more time.

This can be done since a person feels pain because of a gene. It helps the brain in processing pain and the condition is known as synaesthesia.

Talking to AAP about the newest discovery, Dr Greg Neely, from Sydney's Garvan Institute of Medical Research said, "So it's not really killing pain as much as diverting it into other sensations. The pain signals would go to the brain and then get re-routed, and instead of going to the pain centres it would get driven into the vision, and the hearing, and the smell processing centre."

The gene that causes pain is called a2d3 and it has been long targeted by painkillers for reducing pain. The studies have been carried on mice.
