Best Answer

US standard traffic warning signs are yellow background with black symbols or letters.

Traffic warning signs in other countries are generally white or yellow background with a red or black border in a triangular shape.

Industrial warning signs are various colors, including OSHA and ANZI standards with orange background and black lettering. A yellow OSHA or ANZI sign would mean "caution" not "warning".
