Bea is the only female in the group, so she is indeed the one who shares a color scheme with Phineas. (I'm kind of disappointed you only brought this resemblance up now- it would have made a great idea for a TSG cartoon.)

Disney also reports that Phineas and Ferb was the #1 animated series of the summer for kids 6-11 for the second year in a row and also took that crown with tweens 9-14. I would make a "summer really does belong to them" joke, but...oh, I just did.
