because they don't go blue, red, purple or yellow
These are nimbostratus clouds. They are low-lying, thick, and usually associated with continuous precipitation like rain or snow. When these clouds appear in the sky, it often indicates prolonged periods of wet weather ahead.
They appear grey because of excessive radiant heat build-up, when heat gets trapped under the sun (the sun's reflection; which produces heat), they then turn grey, the heat radiants form, the sun forms these clouds. At first they may appear as blue clouds but they eventually turn grey, sometimes though they are grey, if a grey cloud is shined through by the sun meaning light passes, the cloud turns blue. Heat radiated clouds, meaning heat buildup from the sun cause different clouds to form, grey clouds can be grey but in the first stage they are blue, sometimes buildup is excessive and you don't see the blue buildup, from above grey clouds may appear blue if it's all grey, but sometimes white are on top of grey clouds. There are three clouds that distinct them from other clouds, grey clouds also sometimes don't produce rain and have short wavelengths thus vanishing themselves. Grey clouds are clouds formed, there are three clouds that form, blue clouds (grey clouds) heat radiated culumus fractus, black clouds (heat radiated clouds formed with different pH water droplets), lastly there are red clouds (scarce); these form because of different explosions one may coin a sun explosion causes these. Grey clouds don't form from white clouds, white clouds are sometimes on top of grey clouds. Black, grey (blue) and red are distinct clouds; no cloud is alike. Also the sky is blue, grey is not apart of the rainbow as on ceases to know, the sun generates heat, what happens when an explosion happens grey or black skies form that is the same with clouds, heat creates these clouds, the suns heat. The main suns reflection along with it's other reflections form these clouds. The suns heat gets trapped in the upper atmosphere thus forming grey clouds. That is why you sometimes see separate build-up's from these clouds. Please excuse my writing also. Hope I help.
When it rains, the sky appears gray because the clouds are blocking sunlight from reaching the ground. This overcast and cloudy condition is often associated with precipitation.
The grey clouds near Earth's surface are called stratus clouds. They are low-lying, uniform clouds that often bring overcast skies and light precipitation.
After it rains, the water either evaporates, soaks into the ground, runs off into rivers and streams, or collects in puddles. This water can provide hydration for plants and replenish groundwater sources.
When it rains, clouds form in the sky due to the moisture in the air condensing. These clouds appear gray because they block sunlight from passing through, causing the sky to appear darker. This gray appearance is a result of the clouds' thickness and the way they scatter and absorb sunlight.
When is is a grey cloud it rains and when it is whit it doesnt

Dark rain Clouds are clouds that are black when it rains
Dark rain Clouds are clouds that are black when it rains
cirrus clouds
they have lots of moisture in them, so when it rains or snows, they go white or lighter again.
depends on what kind of clouds, if it were white clouds the sky would be white. if it were grey clouds it would be grey
the water cycle. the rain builds up in the clouds then it rains
nimbostratus clouds
Nimbus clouds; they are usually a sign of heavy rains.
because they are filled with rain
