Those were very helpful. I'm going to say she is indeed a vanilla. She has the deeper golden color that distinguishes between fire and vanilla, and those babies leave little doubt. They look a LOT like my vanilla mojave girl from 2012. I hope you don't mind a pic or two to show you what I mean.
The top snake is a fire, and the bottom a vanilla. See the noticeable difference in hue?
This is their beautiful Vanilla Mojave girl.
I don't think there is any question mom is a vanilla, at least as far as I am concerned.
Congratulations!!
