During their ABC interview, the twins said they believe Adolf Hitler was a good man with great ideas, such as eugenic standards and incentives to improve the genetic quality of the German people, and marriage loans to help qualified German families begin upon a firm financial basis. In the interview, the twins described the Holocaust as being exaggerated.
They describe their ancestry as English, Scottish and Prussian. The band was named after the color Prussian blue, as a reference to the girls' Prussian heritage and their blue eyes. They also stated that they think Prussian blue is "just a really pretty color". In an interview with viceland.com they added: "There is also the discussion of the lack of 'Prussian Blue' coloring (Zyklon B residue) in the so-called gas chambers in the concentration camps. We think it might make people question some of the inaccuracies of the 'Holocaust' myth."
