Red vs green exit signs
Red and green exit signs are both common in the US. Which one you need depends on your local code, not federal rules.
What federal rules say
OSHA requires exit signs to be distinctive in color and legible, but does not specify red or green. NFPA 101 likewise focuses on visibility, listing and illumination rather than a specific color.
Why some places specify a color
Local building codes can set a color. Red is a long-standing tradition in much of the US; green follows the international running-man convention and is common in newer construction and in some jurisdictions. Because local amendments vary and change, the only reliable answer is your local code and your AHJ.
Stay consistent
Whatever color you use, keep it consistent within a building so occupants are not confused. Mixing colors during piecemeal replacements is a common inspection comment.
Why bi-color signs simplify ordering
GLS exit signs are red and green models, which makes it easier to standardize across properties in different jurisdictions without stocking two separate SKUs. See our exit signs.

Are red or green exit signs required?
Neither is required by OSHA. Local codes may specify a color, so check with your AHJ.
Can I mix red and green exit signs in one building?
