Can a Redhead Have Pearly White Teeth?

I'm a natural redhead male, 20 years old, and I have braces. I get them off in about 6 months and am definitely wanting to have them whitened. I've been researching whitening procedures and am curious if I can even get the teeth shade I desire? My mom told me when I was younger that being a redhead, it's nearly impossible to have extremely white teeth and they'll always be a yellow shade. Is this true?
