How does the combination of blue and green screen work? Why two
colours, IOW?

I was just trying to point out that you don't have to use blue, green
is another colour that is widely used, the main point being is that
the colour of the screen shouldn't clash with the colours that are
going to be placed against it - otherwise there is the possibility of
a presenters shirt (for example) also becoming invisible !...

Oh right. Yes, I'm aware of the problem of bits disappearing - I might have
to use a different colour - had a look at Stingray, and it has
bluey/tourqoisey bits. Perhaps a custom panel done in Cadmium Yellow (which
looks orange, and is very opaque) would be a better idea...
