As far as I can make out we only see colour because of various gases witin our atmosphere & the natural sunlight that basically beams through these chemicals i.e. our Earths Atmosphere as a spectrograph that bends each particle of light into various lenghts which give us an equation of colour so we recognize our blues,greens etc..yet the U.S. Astronauts that appear on "The Moon" display the American Stars and Stripes in all their glory and also the American banner flaps in an atmospheric" WIND"? All the science that I learnt in my curriculum about rainbows and colours, I believed were true. Have I been misled or were the American Astronauts just actors?
