I love that combination. (In fact, when my youngest son was born, we sent our friends a birth announcement with his name etc in the Gulf color combination... to make sure that everybody knew it was a boy!).
Point is that the orange has a very important role. You can add too much orange, turning the car into a circus act. When you use the orange accent 'wisely', it will lift the blue! Off course, that's all imho!
To show you what I mean: Dutch car maker Donkervoort started its life as builder of Lotus models. He has evoluated into a high end car maker with a 270 hp Audi engine under the bonnet. In fact, Audi uses the Donkervoort for development! To give you an idea about the build quality.
All Donkervoorts have a 'bespoke' costume. This one has a very modest orange stripe. It emphasizes the blue color and it shows the Gulf literary: everybody knows: "Gulf!"
i wouldn't hesitate to turn a 914 in need of a respray into a Gulf car (mmmm, there's a candidate in my workshop now....).
