Dawn
DAWN (the 16th-century form of the earlier " dawing " or " dawning," from an old verb " daw," 0. Eng. dagian, to become day; cf. Dutch dagen, and Ger. tagen), the time when light appears (daws) in the sky in the morning. The dawn colours appear in the reverse order of the sunset colours and are due to the same cause. When the Sun is lowest in both cases the colour is deep red; this gradually changes through orange to gold and brilliant yellow as the sun approaches the horizon. These colours follow each other in order of refrangibility, reproducing all the colours of the spectrum in order except the blue rays which are scattered in the sky. The colours of the dawn are purer and colder than the sunset colours since there is less dust and moisture in the atmosphere and less consequent sifting of light rays.
