Why is the natural ambient light rather red during the sunset?

Question

...and so it is the colour of the clouds, sometimes....

Answer 1

Rayleigh scattering is what causes the sky to be blue. It is the scattering of light by particles in the atmosphere. During the day time, scattering of sunlight in clear atmosphere is the main reason why the sky is blue.

At sunset, the sky will appear yellow, because the light from the sun has passed a long distance through air and some of the blue light has been scattered away. If the air is polluted with small particles, natural or otherwise, the sunset will be more red.

As for the color of the clouds... Red, orange and pink clouds occur almost entirely at sunrise/sunset and are the result of the scattering of sunlight by the atmosphere itself. The clouds themselves are not that color; they are merely reflecting the long (and unscattered) rays of sunlight which are predominant at those hours.

Answer 2

As the sun begins to set, the light must travel farther through the atmosphere before it gets to you. More of the light is reflected and scattered. As less reaches you directly, the sun appears less bright. The color of the sun itself appears to change, first to orange and then to red. This is because even more of the short wavelength blues and greens are now scattered. Only the longer wavelengths are left in the direct beam that reaches your eyes.

Answer 3

As the angle o the light decreases, it travels through more atmosphere, causing the red to scatter. When the sun is high, the blue light scatters, giving the sky its color.

Answer 4

Scattering.

Answer 5

dust particals in the vapor droplets of air bends the natural light causing us to see a red glow or tint.

Answer 6

im not sure but i think its the sunlight through the dust particles in the air.
