f82v: those rainbows

[juergenw]

I also find it puzzling that the one rainbow has different colors than the double rainbow   Red-Yellow vs blue-green. Very special. Might this point to some specific theory or source text?

In my above quoted source (Aristotle's Meteorologica) there is some mentioning of rainbows, the colours ( and how these come into appearance, reflections etc). I attach a jpg with a relevant comparison of the top/red coloured rainbow with the relevant text source (Met 375b1-4). Interesting that the red coloured one is the outermost band.

   

There is more on colour (and the difference, existence, mixture etc in the subsequent text - and there are more text sources in Meteorologica (again, the above quoted article is a great source)
