Choosing between red and green exit signs for your facility is dependent on several factors, including aesthetics and local regulations. For example, in New York & Chicago, Exit Signs must have red letters. Check with your local building codes, fire marshals, or inspectors before purchasing any exit sign. Some safety codes also require exit signs to have white text ("EXIT") on a colored background, while others require colored text on a white or clear background. Most international building codes prescribe green as the color for exit signs.
