The colors tell the story

For most outlets that publish/display radar imagery, red colors show winds moving away from the radar, while green colors show winds moving towards the radar. Darker shading indicates slower winds, while brighter colors indicate faster winds.

A debris ball is a radar signature that "implies" that tornado has destroyed something and is lofting the debris in the air. Well you already know that reds and blacks on radar mean the radar is seeing a lot of rain, hail, or if it is where a tornado should form on radar then it can mean debris.

This often appears as a small blue circle within a larger red area. More than just a debris ball needs to appear on radar for a tornado to be radar confirmed. Another crucial piece of information...

Couplets. It can be tricky to figure out where the radar site is most of the time, but you don't need to worry too much. When you're looking at the radar to spot a tornado, you want to look for...

TO.W. Issued when a tornado is indicated by radar or sighted by storm spotters. The warning will include where the tornado is, direction of movement, and what towns/locations will be in its path. Generally issued based on expected track of tornado, which may include multiple towns, cities, or counties.

As a general rule, the brighter the radar color, the more severe the weather associated with it. Because of this, yellows, oranges, and reds make severe storms easy to detect at a glance. In the same way that radar colors make it easy to spot an existing storm, shapes make it easy to classify a storm into its severity type.

A storm with a tornado observed by radar has certain distinguishing features and forecasters are trained to recognize them. When a Doppler radar detects a large rotating updraft that occurs inside a supercell, it is called a mesocyclone. The mesocyclone is usually 2-6 miles in diameter, and is much larger than the tornado that may develop ...

In looking at radar data from NWS’s fixed WSR-88D radar, things are often not so clear cut. Below is an example from 2015 in North Dakota with an EF-2 Tornado. In the reflectivity (red’s and oranges) and correlation coefficient (Note the color table is reversed from the Dodge City example, Red = lower correlation coefficient), it is not so clear where the tornado debris signature is.
