I had a completely white Civic Type-R Championship White prior to my Golf GTI, even the wheels were white. Believe me when I say it will shine very well when in daylight. The white on my Civic when the car was clean, was literally blinding, and it was a standard paint which was a creamier off white than the Golf. If you are in doubt of it not shining as much as you would like take a look at the threads regarding cleaning your car the right way and give it a polish. Some of the cars on these threads look like the paint is coated in glass they are that shiny. However if you want a mirror like finish so you can see your reflection and wish to polish it regularly dark colours will provide a more mirror like reflection. But personally I have owned black, red and white cars, White wins out every time for me.
