I did some work this evening in simgear/flightgear to track some additional vasi positional information so that I can then compute the angle and correct color. This is a first stab and the result is a gross simplification of what really happens. There are some things I still need to research adn think about, and an item or two I know isn't quite right. But the vasi/papi lights are now colored by your approach angle and not your view angle which is a big improvement. I'll need to spend some more time on this to get the remaining issues ironed out, so please don't panic if they don't look quite right yet.
