where have you seen red = on, green = off?

  Most safety switches on firearms expose a red dot meaning the weapon is "ON"/ready to fire.

    I agree with you on that, but I’ve never seen green be the contrasting or alternative color.

      Maybe because a gun should never be treated as totally safe.

  In electrical industry, red used to mean powered or hot or dangerous, green unpowered or harmless. All earth-leakage breakers in my area are like this: https://en.m.wikipedia.org/wiki/File:Schneider_Electric_A9D31620.JPG https://en.m.wikipedia.org/wiki/File:Schneider_Electric_A9D3... https://i.ebayimg.com/images/g/sHYAAOSwu2ZkBk5~/s-l960.webp https://i.ebayimg.com/images/g/sHYAAOSwu2ZkBk5~/s-l960.webp Electronics industry have diverged.

  In security red generally means encryption/protection is active. And then there is this: https://en.wikipedia.org/wiki/Tally_light https://en.wikipedia.org/wiki/Tally_light > In the active (on air) mode, tally lights are typically red. > Some cameras and video switchers are capable of additionally showing a preview tally signal (typically green) for when the camera is about to be switched to and become the main source of video signal. Once the switch happens, green changes to red.

    > In security red generally means encryption/protection is active. That's daft. You want to highlight (red) the insecure state, and reassure (green)in the secure state.

      Really? Do you want a real-world example have a look at US White House: > President Obama talks on the phone aboard Air Force One. April 10, 2014. > The Airborne Executive Phone has the red light on, which means it's a secure call. https://www.electrospaces.net/2017/01/the-presidential-communications.html https://www.electrospaces.net/2017/01/the-presidential-commu... It is further made more clear because NSA literally calls their secure network the red network.

  red and green should not be used like that. A significant fraction of the population, especially males, has difficulty telling them apart. That's why mains wiring no longer uses red to mean live and green to mean ground.
