How old/big is the turtle? If he's bigger, then he's likely not going to gain back the vibrant green hatchlings have.
A good habitat, basking under proper lighting, and a good diet will improve his shell no matter what. Foods containing beta carotene like pumpkin, dandelions, red bell peppers, carrots, etc. will help enhance coloration.
