I say fire. Vanillas tend to have a thin little mustache on the front lips and are more likely to have to have side lip spots than fires. But the base color of a vanilla is usually more on the orangy side while fires tend to have a more bright and pale look. Vanillas also have more of a abberant pattern while the fires pattern looks like the pattern of a normal.
I bet she is a fire too. Got that little pyramid on her head just like my fire female. My 2 vanillas (one is not yet proven) have a skull head marking but the fires have more of a peaked marking.
