Hholly, the fish that are commonly referred to as "blue eyes" are the Pseudomugils, like gertrudae, signifer, furcatus. Your fish is in a different genus and to my knowledge would not be considered a blue eye. Your celebes rainbow in the photos looks completely normal to me. Your fish will color up more when they get settled down. You can expect them to show some nice blue/green on the body and yellow on the fins. It looks like yours have some maturing to do as well so you can expect the finnage to improve with age. Just wait until you see them displaying for one another (same with the threadfins, BTW). It would be good to add a few more as long as you have room.
