1) That is where the greatest density of particulate matter is.
2) That is where the greatest density of large water / ice droplets are.
A thundercloud typically appears dark and dense, often towering high into the sky. These clouds can also have a flat base, with a top that may spread out in an anvil shape. Thunderclouds are associated with thunderstorms and can bring heavy rain, lightning, and thunder.
Wall cloud.
The wall cloud is a large section of cloud extending down from the base of a thunderstorm. The wall cloud marke the strongest part of the mesocyclone, which is the rotating updraft that can produce a tornado. A funnel cloud or tornado usually extends from the base of a wall cloud.
Many cloud types can lead to a gray sky. Stratus is one of the more common ones.
The low hanging cloud base that spawns tornadoes is called a wall cloud. Wall clouds are often associated with severe thunderstorms and can be a precursor to tornado formation.
The Grey Cloud - 2007 is rated/received certificates of: Australia:M
Blue grey, dark grey, warm grey, cool grey, cloud grey, silver.
No, the wall cloud is a lowered section of the cloud base from which a tornado or funnel cloud descends. The dark cloud at the base of a tornado is called the debris cloud.

I would expect rain to be formed from a dark grey cloud.

Cloud base refers to the altitude above the ground at which the lowest portion of a cloud is observed. Cloud ceiling, on the other hand, is the height above the ground of the lowest cloud layer covering more than half of the sky. Cloud base is the specific altitude at which a cloud starts, while cloud ceiling is the overall height of the lowest cloud layer in the sky.
A nimbostratus cloud is a dark, thick cloud that produces precipitation such as rain or snow. These clouds often cover the sky and are associated with prolonged periods of precipitation.
Wall cloud.
Cumulonimbus cloud's colour depends on the conditions, time and your location. In broad daylight, with the sun shining on them they are usually white, like all clouds in daylight. The base of the cloud is dark grey because of the thick cloud blocking the sun. Depending on the cloud thickness, the underside of a cumulonimbus can even be black. When there is a lot of hail and ice crystals in the cloud, it can take on a green or turquoise appearance. In the sunset, the cloud can appear brown, orange or red. At dusk, the cloud can appear light blue, and at night, it is usually hard to see untill lightning illuminates it.
