I think the colour is fine.
You have to remember 99% of UK new car buyers are sheep and can't see beyond black, white, grey/silver or if they are a bit of a rebel, red.
Which is why VW UK only offer those colours pretty much, because the others available in Germany wouldn't sell.
Although I don't understand that, because offering a colour doesn't actually cost anything other than another one of those plastic paint sample squares for the dealership wall!
