Which color represents reactivity on the NFPA diamond?

Explanation:
NFPA 704 uses color-coded sections to show different hazard types, and the yellow section represents reactivity, indicating how a substance may react or release energy. The other colors map to different hazards: blue for health, red for flammability, and white for special hazards. The numbers in each color (0–4) indicate the level of hazard, with higher numbers meaning greater risk. So the color that represents reactivity is the yellow one.
