Interesting stuff urbanarmitage.  I worked way too late tonight and will probably tomorrow, so I might not be able to do anything else for a few days.

I think the colour reflections you are getting are quite natural.  Light works a little differently then the standard pigment colourwheel we all get taught in grade school.  The three primaries for light are Green, Red and Blue as opposed to Yellow, Red and Blue.  Thus when mixed you might get a different reaction the you would expect from something like oil paints.

svdl thanks for some clarification on what the settings do.  I really hope to get to try some stuff soon.

G-night all!
