Red zone like engine tachometer

[katyshin]

Sorry, maybe I'm writing the wrong way.

Could you add a red zone to the pointers similar to sectors, but which are not drawn from the center, but simply change the color of the scale that fell into it. For example, the red zone of the tachometer engine speed. I do not have enough knowledge to understand the source code...
