That snake is light in color unnaturally. Feed him a nice small rat once a week for a few months and he will get his proper coloration back. The reason he is that color is a lack of nutritional supply, dehydration, and improper temperatures.
People need to stop this whole 'scarring' dispute. I hardly even felt like reading over it, it looked too immature. This snake was a rescue, so I was not surprised to see this animal in such a state. This man is on this site asking for our help, all we can do is correct his mistakes and make sure that the animal is healthy from now on.
Also, I see burns on backs all the time from wrapping lighting fixtures and heat rocks.
It looked like it was healed so I wasn't concerned with it at all. I'm far more concerned about the nutrition that this snake is getting/had received.
