Why is the sky blue? When sunlight reaches Earth's atmosphere, it is scattered in all directions by all the gases and particles in the air. Blue is scattered by air molecules more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Closer to the horizon, the sky fades to a lighter blue or white. The sunlight reaching us from low in the sky has passed through even more air than the sunlight reaching us from overhead. As the sunlight has passed through all this air, the air molecules have scattered and rescattered the blue light many times in many directions. Also, the surface of Earth has reflected and scattered the light. All this scattering mixes the colors together again so we see more white and less blue.
What the color blue says about you!
Blue: Soft, soothing, compassionate and caring, Blue is the color of deliberation and introspection, conservatism and duty. Patient, persevering, conscientious, sensitive and self-controlled, Blues like to be admired for their steady character and wisdom. They are faithful, but are often worriers with somewhat inflexible beliefs and can be too cautious, and suspicious of flamboyant behavior.
