By looking at their lineage it will give you an idea of what they can potentially look like but you will never get a whole clutch that looks like the sire, there will always be variations. Some juveniles show good color early on and some don't and the ones that don't can still look better than the ones that did. It's a crap shoot really, don't give up hope it can take another year for all his color to come in. The guy in my avatar had good color as a juvenile but really got his color after he was a year old.
