Topic: Sky Colors
HAVE YOU EVER WONDERED why clear skies are sometimes deep blue and at other times almost white? Or why some sunsets are fiery red and others watery yellow? The reason is that the mixture of particles in the atmosphere is constantly changing. Every colour in the sky comes from the Sun. Sunlight is white, which means it is a mix of every colour in the rainbow. But as it passes through the atmosphere, gases, dust, ice crystals, and water droplets split it into the various colours, bouncing some toward our eyes and absorbing others. The colours we see depend on which colours are reflected and which are absorbed. Clear skies are blue because gases in the air reflect mostly blue light from the Sun. The sky gets paler when extra dust or moisture reflects other colours, diluting the blue.
Sunsets are yellow (or red, if the air is dusty) because the Sun’s rays have to travel so far through the lower atmosphere that all the yellow light is absorbed.
