What do the different colors for weather signify

Hey, it’s different than a storm scope! Can someone tell me what designations for weather Flightaware assigns the colors they use?

Green = light
Red = really heavy
White = bad day

Thanks for the response. Mostly I see dark and light blue and that’s what I’m not sure of. Usually on a storm scope you have green, yellow and red, and their meanings are obvious. Not sure about the blues though.

Oh, blue is lighter than green.

In increasing intensity it’s blue, green, yellow, purple, white I think.

You mean the intensity scale at the top of this image?
