Correct blue for raf matador

[Listerj123]

I'm just wondering if anyone could help me with finding the correct blue for a raf matador as I've seen some in a dark navy blue but others in a light blue need help finding the right shade

I was chatting to a chap at a local show on the weekend when we took our big Hillman along. He had just bought a civilian pre-war Hillman Minx that has some military magnetic transfers on it.

He was telling me that he has decided to paint it RAF blue as he had seen some wartime Hillmans on Flickr painted that way. I wasnt rude but was chatting that during the war they weren't likely to have been painted that colour but as he said, there are so many restored RAF wartime vehicles painted blue he just wants to go with the others.
