The sun is white. Always has been and always will be.
"When we see the Sun at sunrise or sunset, when it is low in the sky, it may appear yellow, orange, or red. But that is only because its short-wavelength colors (green, blue, violet) are scattered out by the Earth's atmosphere, much like small waves are dispersed by big rocks along the shore. Hence only the reds, yellows, and oranges get through the thick atmosphere to our eyes.
When the Sun is high in the sky, the shorter waves, primarily the blue, strike air molecues in the upper atmosphere and bounce around and scatter. Hence explaining why the sky looks blue.
Some people think that enough blue light is scattered out in the Earth's atmosphere to cause the Sun to appear slightly yellow. What do you think?"

The question to ask and research is what has changed in our atmosphere to cause us to see the sun as more whitish and the sky less blue or is it just over our cities that we see the change?
