When do you think it's appropriate to blow a black whistle, and when do you think it's appropriate to blow a white one?

If one has to blow a whistle the color doesn't matter.

kingkripple does it really matter that much what colour it is makes exactly the same sound and exactly the same effect when blown

Believe me when I tell you, despite what you've heard, that is not a whistle they've been asking you to blow.

I prefer the shiny chrome ones myself...

When you have one available?
