Original color?

Okay guys I know this is a highly discussed topic and everyone seems to have their own opinion but I can't decide if I want to change the color of my car or keep it original. It's a 71 demon and its dark greenish. I don't like the color but a lot of people have told me to keep it original. It doesn't have the original engine in it anyways. I would really like to change it to a blue color but it will also cost more because then I would have to completely redo the interior. I am planning on starting the restoration this winter. What are your guys thoughts should I keep the original green or go with the blue I want?
