Tornadoes often form in a type of cumulonimbus cloud called a wall cloud. Look up what a cumulonimbus cloud looks like on Google images.
Nope, but they can come from Cumulonimbus clouds, which are the same clouds that produce thunder and lightning. See the link below for a picture of what they look like.
There is no particular sky color that indicates a tornado is coming. It is often reported that the clouds look green before and during tornado. But this does not necessarily indicate a tornado, nor is it necessary for a tornado to form. The clouds in a tornadic storm may also appear gray or black.
A cone-like dip in the clouds with tornadic motions which will often precede the touchdown of a Tornado.
A tornado is a vortex and may also contain vortices. A vortex is a rotating body of liquid or gass. In a tornado, the vortex is made visible by condensation or dust and debris. It may look like a cone, tapering appendage, or column attatched to the clouds, or may take the appearance of a tube or swirling mass of dust.
you will see Cumulonimbus clouds before a tornado which are large, dark, anvil-shaped clouds.
a funnel
It is also called a tornado!

Signs to look for: a lowering of the cloud base rotation in the clouds a hole in the clouds at the back of a thunderstorm Swirling dust beneath the lowered clouds
funnel clouds. Other signs that a tornado may soon occur include a lowering of the cloud base and rotation in the clouds during a thunderstorm.
Tornadoes come in different shapes, and the shape changes during the life of the tornado. Some tornadoes are like thin tubes or ropes, some look like large wedges. If it is wrapped in rain, or there isn't enough light, it can be hard to see a tornado. Sometimes clouds may look like a tornado but aren't, so looking for other clues like rotation is important.

The funnel clouds of a tornado often range from white to gray to black.
