In the U.S, we say "exit here". In England, they say "way out" pointing to the exit. It is noticeable that both countries have different ways to describe how to exit a building.  I took a picture of this "way out" sign because it is everywhere in London. This contrast on this sign is very poor in my opinion. The "WAY OUT" is not bright enough to get people's attention and stand out. A better color to use instead of brown would be for example, yellow against a background of black.
