Will Bird is working with lemon & calico black rats, as well. Those are the only real new traits I know of, asides from combinations of other traits (albino brindle, etc. . .). Also, the "hypo" gene is supposedly T albino. It's been said to have been proven out through breeding that T albino, lavender, and hypo are all three the same trait.

I've never heard of Halloween phase, myself, and I was told the stripe gene was introduced from grey rats, but I don't have any proof of this.
