Which street sign is usually red in most parts of the world?

When thinking about stop signs, the first thing that comes to mind is a red octagon sign with white letters saying “STOP.” Nowadays, the color of stop signs around the world are all red. But in the past, some used to be yellow and blue, too. In some countries like Ethiopia, Israel, and Pakistan, the stop sign is signaled by a hand indicating to stop without any text.
