Which of the following is NOT an NFPA 704 color?

Explanation:
NFPA 704 uses a four-color hazard diamond to convey different types of danger: blue for health, red for flammability, yellow for reactivity, and white for special hazards. Each color communicates a distinct aspect of the hazard, with numbers 0–4 indicating increasing severity for the blue, red, and yellow sections, while the white section lists specific hazard notes (like W for water-reactive, OX for oxidizers, etc.). Green is not part of this color palette, so it would not be an NFPA 704 indication. Since the standard colors are blue, red, yellow, and white, green is the color that does not fit the NFPA 704 system.
