I'm partial to silver/gunmetal yes, but the XJ paint was a mixture of Audi/volkswagen gunmetal and something else - what I had in the garage at the time I also like Anthracite and Ferrari red though
But a well-painted bike in any colour will always catch my eye. Don't like green !
I'd like to paint a bike with that "prism" paint that changes colour - I reckon a 1000F in that would be spectacular !

 

I had seen a few years ago a Blackbird in a flip paint colour and it was nice just poorly done. If it had been done properly it would have been amazing.
