Have you ever thought about the function of colours?

We explored the neighbourhood to answer this question and we found an authentic and useful way to use them: The traffic lights.

What does the colour’s

change involves?

If you see the orange colour in

the traffic light, what do you do?

What could it happen if we

change the lights’ colours?

The first traffic light was installed in 1868 in London, operated by gas. Unfortunately it exploded and it was not until 1914, in America, that the red-green systems were installed.
