So, in case you ever get a chance to visit Japan and stand in front of a pedestrian crossing, you might find that the colour of the “go” signal is slightly blue rather than the usual bright green. It might seem like a simple design or technological variation. Yet, the truth behind this variation goes far deeper. The Japanese blue traffic lights are not really blue in the conventional sense. Yet, there is a beautiful mix of language, culture, and historical elements that have been around for centuries. It is a fascinating reminder that even something as ordinary as a traffic signal can reflect the deep-rooted interplay between language, perception, and tradition in a society, revealing how culture quietly shapes even the way we see colour.
