My thought was that Freida is a calico. My calico looks almost exactly like Freida, so if that is considered a tortie then maybe I have a tortie.

But, that's not the point - if this lady is being that picky about this color or pattern, that sounds off an alarm in my head. Listen to your gut feeling and if it's already telling you to run away from her, then you probably should.... I know you'll make the right decision!
