My point is we're seeing a repaint happen and people are complaining.
Looking at those two images, I prefer the orange pipes (though not the huge Fanta logo). It mixes things up a bit, and looks a bit more interesting. As for the sponsorship, I genuinely did not even realise the lack of Coca-Cola logos until I had looked at for a while; bar the Fanta thing, it's completely unintrusive. Maybe it's the fact I haven't finished Alton that much in my life, but when I look at oranges pipes, I see nothing wrong with it...
Fits in nicely with the trend the X Sector rides have as well. All the rides are black with a secondary colour - orange, blue, green and yellow for Oblivion, Submission, Enterprise and Smiler respectively (unless I'm imagining things..). It's not like it doesn't 'fit in' with the style, and it just makes things look a bit better.
I see nothing wrong with it at all..
