Looks fine to me. I think those guys do at least some research.
Anyway, after so long outside, exposed to the elements, the original colors are going to be severely altered. Still, you can see the yellow on the rudder, and that there is yellow behind the cross and covering a tiny bit of the rear canopy fairing.
I would venture to say that the plane was over-painted sometime in service, and that's why there's another yellow band further back.
If you're worried about the "brightness", don't. She will be dull and grungy in no time
They did fine on this one:
