It is a very rare two tone paint job that improves the look of any car, IMO. For one that works, look at the Spyder with the Gulf Porsche paint scheme (light blue and orange).
Just plain stripes doesn't look good because a.) It is small car, b.) It is a convertible (so stripes don't continue over the top), and c.) frunk and rear details (in the front you have that indented V and in the back you have the slots and other openings).
