What does black mean on a radar?
As you know, dark colors like red or black = bad! Those colors mean lots of energy is being reflected back to the radar from things like hail or tons of heavy rain. Since the radar can see anything (even non weather items), then we can get "bright" spots sometimes on radar when we are tracking tornadoes.
What does pink mean on a radar?

What does purple on velocity radar mean?
Purple indicates "range folded" areas (areas where the radar is unable to determine the radial velocity). Composite/Base reflectivity image comparison. The direction of the wind can be estimated using this transition zone.
How can you tell the difference between rain and hail on radar?
