Usually, we see the sky as blue during the day, but at sunset the colors keep changing: sometimes bright orange-red, sometimes soft pink. At each time of the day, the sky wears a different \u201ccolorful outfit.\u201d<\/span><\/p>\n

Sunlight is not just one color but a mixture of many. As it passes through the air, dust and air molecules scatter the colors in different ways.<\/span><\/p>\n

During the day, blue light is scattered the most, making the sky appear blue. But when the Sun is near the horizon, light travels through a longer path. Blue, violet, and green are scattered away, leaving mostly red and orange light for our eyes\u2014painting the sunset sky in glowing colors.<\/span><\/p>\n
