why do the clouds look in diffenrent colours?

Answer 1

A cloud's colour depends chiefly on the cloud's relationship to the light of the sun.In some cases, it depends on the colour of the surrounding sky.If the cloud covers the whole visible area of the sky,the depth of the cloud determines the colour of the cloud;the deeper it is, the darker it is.
When sunlight falls on a cloud,the water in the cloud can either reflect the light back to space or absorb the light.In both the cases,the intensity reduces.
If all the wavelengths of the sun's visible light(red to violet) are not blocked but scattered equally,the result is white light.
So,if the sun is shining and the cloud is not covering the sun,in general, the cloud is white.
Sometimes if there are particles in the atmosphere, the angle of the path,the sun's rays must travel through them can result in preferential scattering of wavelenths so that a particular colour, like gold, predominates in a cloud.This is the same reason that the sky is predominantly blue,because blue wavelength are the most scattered.
At other times,when the sky is orange,for example,some of that light is reflected off a cloud,just like a coloured light shining on a mirror,so the cloud appears orange.

Answer 2

Why would clouds appear to be different colors? A relatively rare phenomenon known as iridescent clouds can show unusual colors vividly or a whole spectrum of colors simultaneously. These clouds are formed of small water droplets of nearly uniform size. When the Sun is in the right position and mostly hidden by thick clouds, these thinner clouds significantly diffract sunlight in a nearly coherent manner, with different colors being deflected by different amounts. Therefore, different colors will come to the observer from slightly different directions. Many clouds start with uniform regions that could show iridescence but quickly become too thick, too mixed, or too far from the Sun to exhibit striking colors. Pictured above, iridescent clouds were photographed over Norway two months ago.

Answer 3

Due to the refraction of light.
