You just got him, too - he's likely very stressed out. Some of my uros, when sick or under stress, dull down quite a lot. When under the right conditions - proper temps, lack of parasites, etc - they brighten up substantially. You might get a fecal check done to be sure there are no parasite issues and a vet visit to make sure he's otherwise healthy. He may brighten up. If not, he'll still make a great pet. One of my favorite uros is my least spectacular in appearance - just a dull brown.
