Wait, this sounds like it’s still consistent with stoplights. Green means safe/off and you can interact with said machine (equally for cars, you can interact and drive through) whereas red means danger/energized (for cars, you should not interact with driving and stop the car). For me, this sounds like it checks out! 👍

Reply to comment by dimonium_anonimo in Eli5 why do traffic lights have red, yellow and green color? Why not use other colors so that even colourblind people can drive. by [deleted]
