As already said, pictures will not do Oryx White justice and, in the right conditions, it looks amazing but, additionally, there are two main factors to take into account.
One, 80% of the British weather is grey. If I lived in a sunny country or at least a country that has actual seasons, then I would go for pearl white paint as that's where you get the best from it. As soon as you get any kind of cloud, the car just looks like a dirty off-white.
Secondly, you have to keep the paint really clean. Again, any kind of obvious visible dirt anywhere on the car - I know mine accumulates dirt quick up the back and on the top of the rear bumper - and it makes the whole car look as though it is just unwashed white.
In perfect conditions, it is really nice but, on an everyday driver in the UK, it's really not that great, in my opinion.
