When sunlight travels through the atmosphere, blue light scatters more than the other colors, leaving a dominant yellow-orange hue to the transmitted light. The scattered light makes the sky blue; the transmitted light ultimately makes the sunset reddish orange.
Model the scattering of light by the atmosphere—which makes our sky appear blue and our sunsets red—by shining a flashlight through clear hot-glue sticks.

Apr 4, 1999 ... Thank goodness everyone asks why is the sky blue and no one asks the much harder question of why is the sky bright. The Short Answer. The molecules which make up 99% of the earth's atmosphere do not absorb any wavelengths of visible light. Molecules in the air are not like indigo molecules which ...
Jun 19, 2001 ... Lighter gases high in the ionosphere, like hydrogen and helium, make colors like blue and purple, but our eyes cannot always see them in the night sky. Good photographic film can be more sensitive to some colors than our eyes. Eyes see best in the green-yellow-orange part of the spectrum, where the ...
