Is it normal that my Calico cat has a half black half pink nose?

my kitten who is 9 weeks has a half black half pink nose. she doesn't have black spots anywhere else but it HAS been there since she was 4 weeks when we got her. her mom died supposavly by coyotees when (we think) she was 2 weeks old. im not worried im just curious if its normal for CALICO cats because i know its typically fine in Tabby Cats. also do you think a good Tabby Cat name is Tabitha?
