We also see the Rayleigh effect at play in: -Sunsets where the sky is red.Light has to pass through a larger part of the atmosphere when the sun is lower on the horizon. Red, orange and yellow ...
Hence, the result that when looking at the sky away from the direct incident sunlight, the human eye perceives the sky to be blue. [4] The color perceived is similar to that presented by a monochromatic blue (at wavelength 474–476 nm) mixed with white light, that is, an unsaturated blue light. [5] The explanation of blue color by Lord ...
The color of light from the sky is a result of Rayleigh scattering of sunlight, which results in a perceived blue color. On a sunny day, Rayleigh scattering gives the sky a blue gradient , darkest around the zenith and brightest near the horizon.
Apart from the Sun, distant clouds or snowy mountaintops may appear yellow. 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. [10] At higher altitudes, the sky tends toward darker colors since scattering is reduced due to lower air density.
Solar ray 1 is the lowest from the Sun – the Sun is set. Solar ray 2 is reflected in the (snow) clouds to the observer. Alpenglow (from German: Alpenglühen, lit. 'Alps glow'; Italian: enrosadira) is an optical phenomenon that appears as a horizontal reddish glow near the horizon opposite to the Sun when the solar disk is just below the horizon.
All of the colors shown below in the section shades of azure are referenced as having a hue between 195 and 225 degrees, with the exception of the very pale X11 web color azure – RGB (240, 255, 255) – which, with a hue of 180 degrees, is a tone of cyan, but follows the artistic meaning of azure as sky blue.

Some of the most varied colors at sunset can be found in the opposite or eastern sky after the Sun has set during twilight. Depending on weather conditions and the types of clouds present, these colors have a wide spectrum, and can produce unusual results. [citation needed]
