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.
Sun dogs are red-colored at the side nearest the Sun; farther out the colors grade through oranges to blue. The colors overlap considerably and are muted, never pure or saturated. [5] The colors of the sun dog finally merge into the white of the parhelic circle (if the latter is visible). [6]
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]

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 colors are usually pastel, but can be very vivid or mingled together, sometimes similar to mother-of-pearl. [7] When appearing near the Sun, the effect can be difficult to spot as it is drowned in the Sun's glare. This may be overcome by shielding the sunlight with one's hand or hiding it behind a tree or building.
From velvety purples to fiery reds, many people can see a spectrum of vivid colors via the human eye. Others, however, may have limited hue perception due to certain conditions.. Animals, on the ...
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. [1]
