Normals are probably the most varying morph out there. There's a VERY large range of what the hatchlings in question could look like. Caramel tends to affect snakes even if het form. They may end up being a little warmer than a snake without a Caramel het.
However, I believe Caramel IS masked when Anery (A, not sure about B) is involved.
There's not really a great way to predict what your normal hatchlings would look like exactly. If you want to start a project combining Gold Dust/Charcoal maybe look around and see if you can get some project animals from an established breeder.
If you simply have two snakes and want to breed them just for the hell of it.. please do your research and breed responsibly, not just because you have a pair.
