Seem to have no source for the actual colouring of VN813 at Farnborough, but the blue scheme would most likely have been applied just for the show. I would guess at a blue not far removed from the Petter blue of prototype.
One thing though, VN813 spent most of its life on Nene development with Rolls Royce at Hucknall (near Nottingham). Consequently it still had Nenes when on the De Havilland trials for the rocket motor so should really be shown with the larger engine nacelles housing the Nenes. These are obvious on Ian's photo of VN813 and also shown well on the attached.

Don't suppose anything can be done about it for the sim model though. ;-)
This pic shows 813 with Scorpion fitted and under static test.

As you can see, 813 was in Bomber Command Scheme at the time.
Sorry for the poor quality scans.
