Mike, thats a great question. My theory on it goes like this.
Sincxe the amel is taking away a few layers it really shows whats underneath it all. What I am saying is that in wild form they all pretty much look the same with tiny differences.But once converted over to amels there is a wide aray of colors hidden or masked if you will.
I have seen this with many many types of snakes.Look at the ruthveni for example.In the wild they are very dirty looking ugly snakes.But once line bred and then showing the amel gene you see white to yellow to combos and the red varies as well. Same thing with the hondos.
Even amel corns come in orange or red or whatever yet in wild form they look the same.
Thats always been my take on it.
