I'll second that, I instantly thought pastel lesser/butter. It looks a little more blushed than that combo typically looks but not enough where I would think it has another gene. Pretty snake!
That looks just like my butterfly girl (butter fire pastel). I'm pretty sure yours is a lesser/butter fire pastel too.
The head and the color around the dorsal spots looks to me like indicators of the fire gene in the mix, plus it looks too bright to just be a lesser pastel. Would love to see better pics if her to know for sure, the first pic isn't showing up for me.
