A simple buzzer activating a few knots before stall will get your attention, don't need a weird colourful screen.

That is what I have in my Cub Clone that I am planning to use for flight training because I personally think it is an awesome teaching tool.

This subject got me to thinking and I can not recall ever stalling any airplane unintentionally including Beavers.
I have unintentionally stalled the Pitts and the Decathalon a few times while aggressively practising aerobatics but that is something that I suppose is not really unintentional because I was aware that I was at high risk of the thing stalling considering how I was flying it.
