Can you post a few pictures of him. Try to show his nails, his belly, his tail from above and a general picture from above.
Some morphs like leatherback or dunner are dominant if he has them they will be displayed. If the dominant genes aren't displayed they do not carry them. Others like hypo, trans, zero, witblits ect are recessive and will only be displayed if he got a copy of the gene from both parents. Those may or may not be displayed. If he gets a copy from one parent and not the other that is called being het (heterozygous) if thats the case the only way to know if he has those genes is to breed him with another that is known to carry it. It's called proving them out. We can't tell you any hets he may carry but with pictures we can tell you any morph that is displayed.
Colors are not morphs.
Morphs can be reproduced reliability.
Color is more like melting some crayons and swirling them together, you kinda have an idea but can not accurately predict or reproduce them.
