Calico Chinese Beauty Question
 

I've been looking at chinese beauty snakes(Orthriophis taeniurus taeniurus). I have a question regarding the calico gene. I have seen snakes that have more gray and brown speckling and I have also seen calicos that are more orange and white. Are the orange and white snakes a two gene snake? Are they hypo calicos or are these just two different lines of calico? I'm putting links of both here. These are not my pics, just pics I found to represent exactly what I'm asking.
