There are certain lines that tend to darken more than others. My sinaloans don't get dark at all, but they've got some apricot in them.

I think, and this is going back a way, when they were first importing them they were mixing sinaloans with conanti and smithi, both of which tend to get more black in their white bands.

There has been a lot of selective breeding here in the States to get the white as white as possible.

Craig Trumbower used to be big into sinaloans and had some pretty clean ones. I don't know if he still breeds or not but if you can find him he would be a good place to get clean babies.

I think Bryon Barczyk works with or used to work with them as well.

The one in the picture is not a particularly good example of what is available.
