Years ago the color of stop signs were yellow in some countries, even in the U.S. The major countries decided to have specific designs for sign to be the same in all countries. Now you can go to any, up to standard countries and they will have a red six sided stop sign and red triangle yield sign and others. This is the main reason for the color and the shape.

Nitrix is correct, red is considered a warning. It's also why your temp. gauge is considered "in the red" if your car is overheating. Red is a color that will get your attention.
