Oh, as a follow-up:
Here's the typical 190A-4 style paint scheme:

However, here's a photo of the plane in question:

It doesn't seem to be an actual camo scheme, rather a single color slathered over everything.
I think there is something wrong with the photo. It almost looks as if all the colors (even on the nose) are washed out with this color. Either there is some sort of temporary wash on this plane, or maybe the photo has been damaged, or the Brits painted it over hastily the second they got their hands on it.
I don't know about the last idea, because they probably (??) would have painted over the national markings while they did this.
