in the above context, I would like to further say that sun's original color may be like " the electricity waves in the thundering clouds", and when such whitish light enter in our atmosphere it appears like yellow, or reddish in the morning and in the evining, these are the impacts of "carbonic layers" on the horizones both at east side and at the west side, as appear when we are in the directions to the sun at the time of sun rise and sun set. the original color of light of the sun is mostly white. !
