This article is about Earth’s sky. At sky’s the limit book pdf, the sky appears to be a mostly dark surface or region spangled with stars.
Moon, planets and stars are visible in the sky. A greater proportion of blue light scattered by the atmosphere relative to red light. Civil, nautical, and astronomical twilight. Individual water droplets exposed to white light will create a set of colored rings. If a cloud is thick enough, scattering from multiple water droplets will wash out the set of colored rings and create a washed-out white color.

Far away clouds or snowy mountaintops may appear yellowish. The effect is not very obvious on clear days but is very pronounced when clouds cover the line of sight, reducing the blue hue from scattered sunlight.

However, in twilight, the period of time between sunset and night and between night and sunrise, the situation is more complicated.
