Why so dogmatic, you guys?
If a choice of livery had to be made for the UK Hunter fleet between having them all in various authentic RAF schemes (on the one hand) and flamboyant non-military ones (on the other), it would be a no-brainer.
The appeal of Miss Demeanour's paint-job, however, is its uniqueness. As a flying machine, we non-rated cognoscenti think of the Hunter as a very fast, aerobatic jet aeroplane, whose design is unlikely ever to be matched for sheer beauty. Her raison d’ętre was military, but we don't have to know that to recognise her aesthetically, and we don't have constantly to be reminded of it in her make-up.
The art-work itself, if money was no object, could no-doubt evolve into something even better by annual experiment. But none of us is footing the bill...
