I thought I read recently that vanilla was an allele of fire. It was news to me so if anyone can also confirm that please? I am pretty sure vanilla wasn't mentioned as being in the yb/specter/whirlwind/gravel/spark allele complex. Vanilla does have a super (different looking homozygous version), it's just not very leucistic like but I guess I could see it being related to the fire/lemon back/ember/sulfur (which may or may not be related to each other) based on the hets all being bright.
