Here is a link showing a blue ghost/hypo: http://www.grazianireptiles.com/coll...lanistic-2.jpg

I have seen yellows refered to as butterscotch and visa versa, and the Graziani website says: "Here at Graziani Reptiles, we have proven several different Hypo mutations to be compatible and they are as follows: Blue Ghost, Green Ghost, Yellow/Butterscotch ghost and orange ghost."

This is where I get confused as everyone has a different name for different color variations and I can't tell which are different genes or just different color mutations of the same gene.

What about the pastels? Lemon vs jungle vs mandarin vs .. ?
I'm thinking they are all the same gene just different color expression, and thus compatible.
