Tornadoes are produced by thunderstorms. The circulation of a tornado starts within the clouds and extends downward until it touches down. The tornado does not stop at cloud base either, and can extend several miles up into the storm.
The top of a tornado is actually located several thousand feet to several miles up into the clouds. There is no specific name for it.
Air moves up in a tornado, but in the process of forming, most tornadoes start as a vortex high up in the clouds.
Before a tornado, you may see dark, low-lying clouds with a greenish tint, known as wall clouds or shelf clouds. These can be associated with severe weather and serve as a warning sign for potential tornado activity. Additionally, you may observe ominous rotating clouds or a funnel cloud forming, which can indicate an imminent tornado.
The only cloud you will actually find inside a tornado is the condensation funnel. Other clouds, such as the wall cloud and cumulonimbus are outside the tornado itself.
They don't need to be any color in particular. Though they are often green. The clouds near a tornado and even the tornado itself may appear orange if it occurs near sunset. Clouds near a tornado can also be gray or black.
In a tornado, cumulonimbus clouds are most commonly associated with severe weather and thunderstorms. However, it's the rotating updraft within the storm that causes the formation of a tornado, rather than specific types of clouds.
There is no set size for a wedge tornado. Generally a wedge tornado is one that appears to be wider than the distance from the clouds to the ground and the height of the clouds can vary.
The cloud of condensation the a tornado produces is funnel-shaped, wider at the top than at the bottom.
A tornado is typically spawned from a supercell thunderstorm cloud, known as a mesocyclone. These types of clouds are characterized by a rotating updraft, which can produce the necessary conditions for tornado formation.

Cumulonimbus
Tornadoes are typically associated with severe thunderstorms, which are characterized by towering clouds known as cumulonimbus clouds. It is unlikely for a tornado to form without the presence of clouds, as tornadoes require specific atmospheric conditions and interactions that usually occur within a thunderstorm system.
