Not surprisingly, there was a bit of an outcry about this and the council did eventually concede that there could be a slightly wider interpretation of 'blue' in that it didn't have to be the one particular shade previously stipulated.
With me so far? Good.
So, having dealt with the cab drivers, the powers that be then turned their attention to private hire taxis and yes, you've guessed it, to avoid confusion, they can now be any colour except blue! Private hire taxis which have the misfortune to be blue (any shade) will no longer be licensed. Well, it is understandable. After all, there is so little difference between a cab (big) and a private hire cab (much like any ordinary car) that the public could so easily be confused.
And on the bright side, car resprayers are going to be doing a roaring trade. You really couldn't make it up!
