Orange ghost does leak through in some hets; my breeder female het OG is an example of this. She is very light, has hints of orange and shows more grey than brown-she looks better than some adult ghosts that I have seen. Her male het partner (also proven breeder) is very dark and you would never guess that he is carrying a ghost gene. The bottom line is that you can pick out some of the hets but certainly not all of them and appearance is no guarantee.
