What Is Difference Between "Ghost" Morphs?

Can anyone explain to me what makes Orange Ghost different from regular Ghost or Green or Blue Ghost or any other morph with ghost or hypo in its name?

I don't see a significant difference, but they must be different if some are non-compatible?


Thanks,
Kaleb

Some hypo lines are compatible, and others are not.

Among the lines that are compatible, the difference is in selective breeding for color. It's important to look at the parents when buying hets, so you know you're getting a strong example of the color the hypo is claimed to be.
