They are often dark gray or even black, but not always. In terms of color they could look like fairly ordinary storm clouds.
The funnel cloud of a tornado is full of water droplets just like an ordinary cloud. As a result it blocks light and may appear dark. A tornado may also appear dark if it is lifting large amounts of dark soil into the air. However, not all tornadoes are dark in color. Front-lit tornadoes may appear light gray or even white. Depending on the soil some tornadoes may be light tan, to reddish brown, to gray in color.
No, it can not happen. You will always need a cloud to form a tornado. The kind of cloud that a tornado uses is a cumulonimbus cloud.
The condensation funnel of a tornado is basically a cloud formed when moisture inside a tornado condenses and in that sense it is similar to an ordinary cloud. The debris cloud of a tornado is a cloud of debris picked up by a tornado usually from buildings and trees the tornado has damaged or destroyed.
Dark gray and flat or really dark almost black and puffy
A tornado that does not touch the ground is a funnel cloud.
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.
Most likely it is a funnel cloud. If it touches the ground then it is a tornado.

The cloud that forms the visible part of a tornado is called a funnel cloud.
It is often dark during a tornado not because of the tornado itself, but becasue of the parent thunderstorm. The thunderstorm consists of a very tall cumulonimbus cloud, which blocks out most sunlight.

The water droplets coming out of vapour phase in a cloud reflect sunlight. This makes the sunwards side of a cloud shiny white and the opposite side of the cloud dark and grey.
No. A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground. A tornado is often, but not always made visible by a funnel cloud. But the tornado is not the cloud itself.
A tornado that does not touch the ground is a funnel cloud.
First, the storm itself has to be rotating. A downdraft from another part of the rotating air and tightens and intensifies it into a tornado.
