Answer: Lots of water will help your lawn green up. Water deeply once or twice a week and in the fall, fertilize with a 21-7-14. As for matching the lawn, you may have to dig some of it up and take it to a nursery or Cooperative Extension office to identify the types of grass that your builder installed. Then you can match the grass seeds to the turfgrass that you like the most. Fall is the best time to reseed.
Good luck with your lawn!
