Thanks David for this very informative post, I am looking forward to your book and the new research and material it will reveal.

I will leave it to others to speculate about the colors of this particular plane, though, but for me one question remains - Maybe I am totally blind or the contrast levels of my screen are gone somewhere over the rainbow, but WHERE is the numeral "3" on this plane?? I don't even have the slightest idea, even after prolonged staring...

Cheers,
Christian
