No trickery of any kind, that's the image as it came out of the camera, all I have done is a bit of cropping. The image is a touch overexposed (+ 1 stop I think I recall) for better rendering of the cockpit interior.
I've no idea why such a garish colour was applied (not, I suppose, can I say for certain whether it's been re-painted since it ceased flying), but I'd be interested to find out. Certainly not the most restful of hues...
