No, they weren't going to get to stay out ... that is why God gives children adults!
Thunderstorms are gorgeous from a safe distance ... never seen one black and green in person with a roll, but I know of what you speak ... rarely also do we have big thunderstorms here, but I imagine that was a magical moment that you saw indeed ... I wish I had a camera the night there was so much lightning the colors could be distinguished ... lightning comes in all the colors of light ...
I have seen it, in a reddish color.
Red is a indeed common color!
