A clear cloudless day-time sky is bluebecause molecules in the air scatterblue light from the sun more than they scatter red light.
During sunrise and sunset, the rays have to travel a larger part of the atmosphere because they are very close to the horizon. Therefore, light other than red is mostly scattered away. Most of the red light, which is the least scattered, enters our eyes. Hence, the sun and the sky appear red.
The primary reason why the color redis used for danger signals is that redlight is scattered the least by air molecules. The effect of scattering is inversely related to the fourth power of the wavelength of a color. ... So redlight is able to travel the longest distance through fog, rain, and the alike.
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 toappear slightly yellow.
Unlike scattering in the sky or ocean, in which molecules are so small they only scatter blue and violet light, water droplets are large enough the scatter the entire spectrum. That's why cloudsappear to be mostly white. There are times when clouds may not appear to be totally white, even on a sunny day
