Why isn't the sun Green when the peak of the emission spectra is green? [] Why is chlorophil green (reflecting green light) when the peak of solar radiation is green? [] [] Minute physics "why is the sky blue?" [] - though he misses out on "why isn't the sky violet?" which has to do the with lower emission from the sun at that range of wavelengths, our lower sensitivity at the violet wavelength and the mixing of multiple wavelengths producing our perception of blue: Why isn't the Sky violet?" : []
